Google's New AI Tool Already Beaten? Try Alibaba's Free Local Alternative Last week I was figuring out how to access Google's Nano Banana Pro—dealing with VPNs, subscriptions, and daily usage limits. Then Alibaba dropped a bombshell: Z-Image-Turbo, a completely open-source AI image generator that runs locally on your machine with zero restrictions. I downloaded the one-click package and tested it immediately. This tool is absolutely brilliant. To be honest, previous attempts with Stable Diffusion to generate posters with Chinese text were disastrous—the characters would come out completely distorted. Z-Image-Turbo completely solves this pain point. I simply typed "a girl in traditional Chinese hanfu playing a guqin in a bamboo forest," and the output was stunning.

Hook: Your Bank Account is in its Flop Era. Let's Talk About It. No cap, you look at your bank account and wonder where all the money went. That iced latte is now the price of a streaming sub, rent is hitting new highs, and getting a loan feels like you're asking for a kidney. You scroll through TikTok and hear everyone yelling about 'inflation,' 'recession,' and 'the Fed.' It all sounds like a whole lot of noise, something for dudes in suits to worry about.

In the article How to evaluate the quality of a framework technology, I introduced a concept, framework agnosticism, and pointed out that the most ideal framework is one that you are completely unaware of when writing business code. Some readers asked: As of now, no business development is completely independent of frameworks—what is the point of this concept? A helpful classmate in the discussion group replied: Software development depends on frameworks because we need the framework-provided input/output, event callbacks, dependency injection, external data I/O, context, etc.—most of which are side effects that the program’s execution relies on. If, when implementing a piece of business, we design it as a library, explicitly declare all side effects as interfaces and context objects, and …  ( 17 min )

Few programming languages have shaped the software world as profoundly as C. Created over 50 years ago, C still powers operating systems, compilers, embedded systems, databases, and performance-critical applications around the globe. Whether you’re a beginner stepping into low-level programming or an experienced developer exploring systems-level engineering, learning C equips you with a deeper understanding of how computers actually work. In this article, we’ll explore what makes C timeless, why developers continue to rely on it, and what you need to know to get started. What Is C? C is a general-purpose, procedural programming language created by Dennis Ritchie at Bell Labs in the early 1970s. It was originally developed to build the UNIX operating system, but quickly became a universal…  ( 8 min )

With the popularity of low-code concepts and products, many are considering introducing the idea of logic orchestration into their projects—offloading logic traditionally produced via hand-crafted hard coding to a logic orchestration engine that can be flexibly configured. In this article, I will introduce the design philosophy of the logic orchestration engine NopTaskFlow in the Nop platform and analyze the mathematical inevitability of its design. At the end, I will explain why NopTaskFlow is a next-generation logic orchestration engine and what typical characteristics this so-called next generation possesses. When we program using traditional programming languages and frameworks, we are essentially following certain constraint specifications defined by the language, which can be seen as…  ( 37 min )

Chapter 6: Building Your Own Types Monday morning arrived with the scent of rain on concrete. Ethan descended the familiar stairs, coffee tray in one hand, a white bakery bag in the other. Eleanor looked up from her laptop. "What's the occasion?" "Croissants. The baker said they're architectural—all those layers held together by structure." She smiled. "Perfect. Today we're building structures of our own. Sit." Ethan set down the coffees and took his seat. "Structures?" "Structs. Go's way of creating custom types that group related data together. Until now, we've used Go's built-in types—int, string, bool, slices, maps. Today, we make our own."

If you have used Google’s Gemini and found it impressive but ultimately disconnected from your actual work, you aren't alone. Many users describe the initial experience as talking to a very smart stranger—it knows the capital of France and can write a haiku, but it knows absolutely nothing about you, your projects, or your schedule. However, the difference between Gemini being a novelty and a productivity powerhouse often comes down to a single, often overlooked toggle in the settings: The Google Workspace Extension. Out of the box, most AI chatbots operate in function independently. If you want Gemini to summarize a meeting note you wrote last week, you usually have to find the document, copy the text, paste it into the chat, and then ask your question. This friction defeats the purpose o…  ( 7 min )

An interesting question is: when a new framework technology emerges, how do we evaluate its quality? Since the NopORM engine was open-sourced this year, we’ve received some feedback, but most people likely didn’t grasp the theoretical part of NopORM, so the common confusion is: what concrete advantages does NopORM have over other ORM engines? In this article, I’d like to discuss objective criteria for evaluating a framework that do not hinge on personal experience, preferences, or familiarity. Interestingly, some people never read the theoretical parts themselves, but when discussing the gap between domestic and international software technology, their rhetoric is “domestic development emphasizes pragmatism, and the gap in software methodology is huge.” This can only be described as a “Lor…  ( 22 min )

Hey dev.to community, If you play fantasy sports, you know the anxiety of a trade offer. "Is this fair?" It seems like a simple question, but building a system to answer it objectively—in real-time—is a fascinating engineering challenge. When developing fftradeanalyzer.com, I quickly realized that ingesting stats is easy, but calculating "current value" is incredibly hard. It requires building a pipeline that can handle noisy data, rapid context shifts, and complex normalization. Here’s a look under the hood at the technical hurdles of building a real-time sports valuation engine. The Stack Backend API: Python & FastAPI (for async performance).

Quantum Granules: Taming Complexity with Effect-Based Abstraction Quantum computing holds immense promise, but wrestling with its inherent complexity can feel like navigating a dense jungle. How do we abstract away low-level qubit operations and build more intuitive, manageable quantum programs? Imagine organizing quantum operations into reusable, effect-based units, much like organizing files into folders on your computer. The core idea is Quantum Granular Computing: treating groups of quantum operations as single, abstract units called "granules." Instead of directly manipulating individual qubits, we manipulate these granules, each representing a specific effect on the quantum state. These granules aren't just fixed blocks; they can morph and adapt based on context, providing a flexib…  ( 7 min )

Many people are confused when choosing LED light strips: What are the differences between RGB light strips and ordinary single-color light strips? In fact, apart from the different color effects, there are also essential differences in their control methods. Single-color light strips only emit a fixed color (such as warm white, pure white or red), have a simple structure, and usually only have two wires (positive pole and negative pole). As long as it is connected to the matching power supply, the light strip will remain on constantly. If dimming is needed, simply add a simple PWM dimmer or a smart switch. The operation is intuitive and suitable for basic lighting. Each LED of the RGB light strip contains three chips: red (R), green (G), and blue (B). By mixing the three colors, it can present 16 million colors. It usually has four wires: one common positive pole (+12V/24V), and the other three control the R, G, and B channels respectively. It must be used in conjunction with a dedicated RGB controller (such as an infrared, Bluetooth or Wi-Fi controller) and cannot be directly connected to a power source; otherwise, a short circuit may occur. For this reason, RGB light strips can achieve dynamic effects such as color change, gradient, and music synchronization, but the control is more complex. Monochrome light strips excel in simplicity and reliability, making them suitable for scenarios that do not require fancy effects. Therefore, for an atmosphere, choose RGB; for practicality, choose monochrome - provided that the correct controller and power supply are paired.  ( 6 min )

Introduction As a Senior Engineer, I’ve spent 5 years building scalable systems in Java and Angular. When I moved into AI, I noticed a pattern: many models live and die in Jupyter Notebooks. I wanted to build systems that survive in production. Here is how I architected two enterprise-grade ML solutions, focusing on Deployment, Explainability, and ROI. 1. The Architecture: Engineering First Before training a single model, I designed the infrastructure. A model is useless if it can't be queried at scale. Serving Layer: I chose FastAPI over Flask for its asynchronous capabilities and automatic validation (Pydantic), mirroring the type-safety I’m used to in Java. Containerization: Both projects are fully Dockerized, ensuring that the environment used for training matches production exactly. …  ( 7 min )

Introduction One thing that occurs in most programming languages is the desire to have type-generic code, that is code whose purpose or algorithms don’t depend on the type of data. Most commonly, this manifests as the desire to have generic “containers,” e.g., arrays, lists, or sets of some type T where T can not only be any type built into the language, but user-defined types as well, e.g., list of integers, sets of strings, etc. Different languages that support generic containers do so differently, e.g., C++ uses “templates” where type parameters are instantiated at compile-time with specific types, e.g., a list can be instantiated with T = int yielding list. C has only minimal support for generic code via _Generic and preprocessor macros. Some people try to use these things t…  ( 8 min )

Adaptive Gripping: Bridging the Dexterity Gap in Robotics Ever watched a robot struggle to pick up a thin sheet of glass or open a cabinet without a handle? Current robotic grippers often falter on tasks requiring both delicate touch and secure hold, limiting their real-world usability. The solution? Imagine a robotic hand that combines the precision of fingertips with the power of suction. We're talking about a hybrid end-effector, seamlessly integrating a traditional gripper with a miniature vacuum system. This allows robots to switch instantly between gripping and suction, or even use them in tandem for ultimate control. It's like giving a robot the ability to both pinch and stick, adapting to a much wider range of objects and surfaces. This combined approach unlocks a new level of ad…  ( 7 min )

Hey everyone! 👋 3-month journey of DataViz Kit, I’m back with another post. If you remember, I mentioned having a few "techniques up my sleeves" to try and crack the SEO code, especially since Google has been a tough nut to crack compared to Bing. Here is what I’ve been working on this week and how the numbers are looking. 🧪 The Experiments Programmatic SEO / Content Clusters: I started crafting articles for specific use cases. 📈 The Numbers (Week 1 Update) Bing: The growth is steady. The Heatmap Maker is still the star player here, bringing in about 50-100 clicks this week. Google: Still the "silent observer." I'm seeing impressions creep up slightly for new keywords, but clicks are flat. I suspect the changes I made this week will take 2-4 weeks to reflect here. 🛠️ Feature Updates Update: I pushed a small fix to the headers. Coming Soon: I’m experimenting with a new chart type. If the testing goes well, it should be live soon. 💭 Thoughts for the Week If you haven't checked it out yet, try my tool by creating a box plot, and let me know what's your opinion. See you in the next update. ✌️  ( 7 min )

🚀 The Problem: Agents are "Anonymous Ghosts" Building an autonomous agent in LangChain is magical. You give it a tool like transfer_money, and it just works. But that magic is also a security nightmare. If your LLM hallucinates or gets prompt-injected, it can call that tool instantly. The API receiving the request has no idea if it was a valid user intent or a rogue agent. The request is just anonymous JSON. We need Attribution. We need the agent to SIGN its work.

View demo https://codepen.io/kspmultimedia/live/MYaGPmP Hi! I don't usually post much here but here's something I've been thinking about lately: I recently rebuilt this set of progress buttons as a practice project exploring how motion can communicate state change. Each button uses the same dark green fill but expresses progression differently: one flows horizontally, another condenses as it fills, and the third uses 3D perspective for a more dimensional feel. Motion Isn't Decoration — It's a Design Decision *Guide attention Meaningful Motion Helps People — Not Distracts Them Here are some principles I use: Story first, motion second Instead of adding animation to fill space, I ask: "What is the emotional or informational moment here?" Motion should amplify intent, not distract from it. Micro-interactions > big animations Subtle hover states, soft easing, scroll cues, gentle reveals — tiny moments make interfaces feel alive without overwhelming users or slowing sites down. Purpose before aesthetics Motion can highlight hierarchy, signal change, or guide direction. If it doesn't support the user journey, it's just noise. Accessibility is part of animation Reduced motion settings, predictable timing, readable transitions — this is how animation becomes inclusive instead of exclusive. Where I'm Growing Next If you're: *Exploring motion in Webflow or GSAP, I'd love to trade notes. *If you have examples of meaningful motion, share them — I'm always learning. *Just want to connecting, please do :)  ( 7 min )

The Paradox of Documentation Drift 🤖 A few months ago, I hit a wall. Using LLMs, I was shipping code faster than ever. Features were flying out the door. But three weeks later, when I had to debug a module I wrote... I had the code, but I had lost the context. I realized I was suffering from the silent killer of velocity: Documentation Drift. The code evolves, but the map stays static. I tried the "good developer" rituals—comments, Confluence updates, and manually drawing diagrams in Miro. But the moment I merged a new PR, the diagrams were dead. The Validation (We Need Maps, Not Books) 🧠 The answers confirmed my thesis: The problem isn't laziness. It's architecture. "Separate docs get stale and are often worse than useless." The truth is: We need living maps, not static books. The Solution: Building MIVNA 🛠️ The Result: Zero Drift, Zero Shadowing 📉 Visual First: Automatically generates high-level architecture diagrams. Legacy Safe: Instantly map that scary legacy module without needing a Senior Dev to "shadow" you for 3 days. Always Sync: If the code changes, the diagram changes. Period. I Need Your Help (Private Beta) 🧪 I’m opening the Private Beta for engineering teams who are tired of "Wiki Rot." I’m not looking for customers; I’m looking for builders to break it and tell me what sucks. Question: Does MIVNA fit your workflow? Do you prefer the diagrams in the PR or a centralized dashboard? 🔗 Check it out here: https://mivna-diagrams.lovable.app/ Let me know your thoughts in the comments!  ( 7 min )

Over the weekend I started the Introduction to Statistics in Python course, what stood out for me is numerical summary statistics - Measure of center. They help us summarize our data but choosing the correct "average" that truly represents the data is very important, else we will be fooled by extreme values. Data can lie to you if you use the wrong average. Imagine 5 kids with these allowances: ₦100, ₦120, ₦110, ₦130, ₦1,000,000 We use mean when the data is symmetrical (evenly spread) because: We use median when the data is skewed (has very big or very small values) because: In Real life: Recruiters use median salary, not mean, so one billionaire doesn't distort pay expectations. Learning this over again, made me understand the topic more clearly. Even on days when learning feels heavy, I'm grateful for every concept I now understand better than yesterday. -SP 🤍  ( 7 min )

AES is a symmetric-key encryption algorithm that is considered extremely secure, very easy to implement, and used in real world. This guide teaches you how to implement its 128-bit CTR mode variant, in C language. The procedure: You randomly generate a 128-bit cipher key You secretly share it with your friend (see note below). Then, when you want to send a secret message, you encrypt your message using your key. Send the encrypted message to your friend. Your friend decrypts it using the key you gave. Note: Secretly sharing the key is done using a protocol like Diffie-Hellman. It's not covered in this guide. You can use the data at link for test data. First half of the guide focuses on implementing the following function: void AES128( uint8_t* block, uint8_t* cipherKey) { } This function…  ( 16 min )

What we're building A repeatable way to boot a cloud GPU (RunPod or Vast.ai), paste a single command, grab the exact ComfyUI version you want, auto-install your favorite custom nodes, and download models from Hugging Face/Civitai into the correct folders. No more “did I put that LoRA in the right place?” or “why is this template six months behind?”. We’ll use a free script generator to produce the one-liner and show you how to tweak, debug, and extend it for your workflow. 💡 Pro tip: Time is literally money on cloud GPUs. Automating the boring parts pays for itself on the first run. If you’ve tried to stand up ComfyUI on a fresh GPU instance, you’ve probably done some combination of: Opening a terminal, then manually git pulling ComfyUI to get a newer version Downloading models piece…  ( 9 min )

Running a business today means wearing many hats. You manage operations, talk to customers, close deals, plan growth, and solve unexpected problems. But while you handle all of that, one thing remains constant: customers will always have questions. And when those questions come in after working hours, during meetings, or when you're away from your devices, you risk losing potential sales, opportunities, and trust. This is exactly why every business, small or large, now needs an AI customer bot. Every time a customer reaches out and doesn't get a response, several things happen. They leave your site, choose a competitor, assume you're unavailable, or simply lose interest. Human support teams can't always be online. Traditional chatbots don't understand real business context. And hiring staf…  ( 8 min )

Lately, I've seen more developers online starting to side eye MCP. There was a tweet by Darren Shepherd that summed it up well: "Most devs were introduced to MCP through coding agents (Cursor, VSCode) and most devs struggle to get value out of MCP in this use case... so they are rejecting MCP because they have a CLI and scripts available to them which are way better for them." Fair. Most developers were introduced to MCPs through some chat-with-your-code experience, and sometimes it doesn't feel better than just opening your terminal and using the tools you know. But here's the thing... MCPs weren't built just for developers. They're not just for IDE copilots or code buddies. At Block, we use MCPs across everything, from finance to design to legal to engineering. I gave a whole talk on how…  ( 9 min )

The Project This week I was trying to work on a simple Deep Learning project to get familiar with PyTorch APIs. Since I had just returned from a staycation where I drove a rental car for over 600 miles, I decided to build a "Car Damage Classifier." I kept the goal simple: the model classifies if an uploaded image of a car is "DAMAGED" or "UNDAMAGED". I couldn't find a ready-to-use dataset, so I created one by merging a damaged car dataset (source: [lplenka/coco-car-damage-detection-dataset]) and a new car dataset (source: [yamaerenay/100-images-of-top-50-car-brands]). I made sure I roughly had the same number of images in my training set to avoid class imbalance. I began training using ResNet-18 as the backbone. Just after 10 epochs, my code reported a validation accuracy of 95.08%. I w…  ( 7 min )

GitHub Home That was in an IoT data processing platform project where we needed to handle hundreds of thousands of device connections simultaneously. Devices generate high-frequency data reporting while requiring real-time control command reception. This bidirectional communication scenario has extremely high requirements for connection management, where any minor performance loss gets amplified into significant problems. In the early stages of the project, we used a popular Node.js framework. In actual deployment, when connection numbers exceeded 50,000, server CPU usage soared to 95%, and response latency increased from a few milliseconds to several hundred milliseconds. Even worse, memory usage grew linearly, quickly reaching the system's physical memory limit. The technical team tried …  ( 9 min )

With thanks to The Oatmeal for the cover art. See also: enshittification. Please consider reading this post on autonomousapps.com instead. This will be my last post on the site dev.to. I’ve been posting my blog to that site since April 2018. My very first post was written when I was the Android team lead at Chess.com, titled Rewriting Chess.com’s Android app. Over the years, I’ve been more or less active, and have published 42 posts in all (counting this one).1 I’ve had concerns about the long-term viability of my presence on that site for a few years, as I’ve observed layers and layers of cruft accumulate around my actual content. I always had higher priorities though, and justified the cruft by recognizing that the site is providing a free service, and it frankly makes posting a tech blog to the internet fairly easy. The last straw came when, after my most recent post, two separate people contacted me about their experience trying to read it (one of them twice). First I was told that there’s a kind of soft login wall when visiting the post. I wasn’t aware of this because, as a writer on the site, I’m always logged in. The wall opens when interacting with one of those annoying popups so common on the Web these days: Note there’s only one option. Clicking it leads to this: Which fortunately can be dismissed. This is a dark pattern. Then later, someone sent me a screenshot of what it looks like after the login cruft has been brushed away: I’ve helpfully highlighted the portions of this screencap that are actual content. 21% of the screen real estate! And more than half the remaining is an ad for some bullshit “AI” product. Let me state this very clearly: fuck “AI.” It’s pure marking speak for a set of technologies founded upon harm, whose primary use-cases are harm. I want nothing to do with it. An auspicious number. ↩  ( 7 min )

Introduction In the world of networking, the OSI Model serves as a universal blueprint for how data travels across networks. Developed by the International Organization for Standardization (ISO) in 1984, it breaks down complex data transmission into seven distinct layers. For developers, network engineers, and DevOps pros, understanding the OSI Model demystifies everything from HTTP requests to TCP sockets in Node.js. It's not just theory—it's the foundation of modern network protocols, helping you troubleshoot and build robust applications. The OSI (Open Systems Interconnection) Model is a conceptual framework that standardizes communication between devices. It divides networking into seven layers, each handling specific tasks like error detection or routing. Unlike the simpler TCP/IP m…  ( 8 min )

Why I built this For many Firebase projects, a lightweight headless CMS is incredibly useful — whether it’s to integrate a small blog, manage app content, or simply provide a structured way to handle Firestore data. There are not many choices which are well integrated with Firebase. In fact its's FireCMS or Flamelink. I like the integration of FireCMS, but for simple projects the full framework can feel a bit heavy. So I built my own alternative using Svelte 4. FireCMS is great in many ways, but for my use cases it often felt like more than I needed. The data model system is impressive, but sometimes the flexibility becomes complexity. The UI also didn’t quite fit how I wanted to work: large tables are hard to navigate, editing inside popups feels clumsy, and handling subcollections neve…  ( 8 min )

Introduction Imagine sending a letter without an address—your data packets in networking face the same chaos. Enter port numbers: the unsung heroes that direct traffic to the right application on a device. In modern networking, port numbers are crucial for everything from web browsing to running a Node.js server. Whether you're a developer debugging connections or a DevOps engineer optimizing infrastructure, understanding ports demystifies TCP/UDP protocols and boosts your troubleshooting skills. Let's dive in. Port numbers are 16-bit unsigned integers (0–65535) that act like apartment numbers in a massive building—your IP address is the building, and the port specifies the exact door. They identify specific processes or services on a networked device, ensuring data reaches the intended …  ( 8 min )

It was supposed to be a smooth EKS migration. Instead, a handful of users started complaining about painfully slow logins — 20 to 40 seconds long. Oddly, others saw no issue at all. What followed was a three-hour debugging marathon that took us through Cloudflare cache rabbit holes, pod benchmarking, and finally, an AWS ALB subnet misconfiguration. What makes this story worth telling is not just the root cause (a bad ALB IP), but the full forensic process — every command, every false lead, and the eventual breakthrough.

If you press your finger against water, it pushes back. That invisible resistance, surface tension, keeps the liquid whole even when disturbed. Good software has something like it. Some systems hold together when you change them; others leak at the slightest touch. The difference lies in integrity — the way a system manages its side effects without losing its shape. I've seen codebases that felt strangely calm, where every possible state meant something real and nothing arbitrary could slip in. Others allowed nonsense to exist, and from there, entropy spread quietly like cracks beneath paint. Type systems, invariants, and boundaries exist to make meaning explicit. They define where things start and stop — what’s allowed, and what isn’t. Without that structure, logic turns soft; assumptions…  ( 8 min )

There's a lot of hype around coding agents and the discourse can be annoying. I've always been into new shiny tools though. I'm forever messing with editors, IDEs, CLIs and anything else that seemed useful. Many of which no longer exist. In college we learned to code in assembly. C seemed very simple by comparison. Then object oriented languages and scripting seemed quaint. IDEs with refactoring and autocomplete made coding much easier. Tools like React and the ability to install npm packages made hacking a UI together somewhat less miserable and then before long somehow much more miserable.

Introduction Fraud and corruption continue to drain the global economy, weaken public trust, and undermine the stability of countries and organizations. The world loses an estimated US$2.6 trillion annually to corruption alone, while businesses surrender about 5% of their yearly revenue to fraud. As digital systems expand and data grows, traditional detection methods—built on manual audits and delayed reviews—are no longer enough. Data analytics is emerging as one of the most powerful tools for identifying, preventing, and combating fraud and corruption. By transforming raw data into actionable insights, analytics exposes hidden risks that humans often miss and strengthens the transparency needed to reduce illegal activities. Understanding Fraud Through Data Fraud is often buried withi…  ( 8 min )

It’s no secret that I use AI as a part of my writing process. But what I have been shy about—at least until now—is laying out the actual process. Not the tech. Not the prompt structure. rhythm. So let’s talk about that. Everyone’s heard the analogy: LLMs are mirrors. They just reflect your words back with more fluff. And yeah, that’s true. exactly why they’re useful. Because if you learn to think out loud—if you’re willing to explore a thought before you’ve fully formed it—that mirror can do something not many human conversation partners can: It reflects your unspoken shape. You put in fog. Here’s what it actually looks like for me. It’s not “open AI, write blog post.” It’s… daily conversation. Every so often, I open up a thread and start talking. And every once in a while—maybe every ten …  ( 9 min )

Sentiment polarity is one of the most commonly referenced outputs of a sentiment analysis model, yet it is often misunderstood. Polarity measures the direction and intensity of emotional tone within a piece of text. A high positive polarity indicates strong approval, satisfaction, or optimism, while a negative polarity reflects criticism, frustration, or concern. Values close to zero tend to represent neutral or balanced language. Polarity is valuable because it allows analysts and applications to quantify subjective language in a measurable way. This makes it easier to sort user feedback, analyze trends, and classify responses automatically. Even though polarity is a simple metric, it forms the foundation for more advanced sentiment and emotion modeling.  ( 6 min )

Real-time codebase indexing with CocoIndex lets you turn a messy, evolving repo into a live semantic API that your AI tools, editors, and SRE workflows can query in milliseconds. Most AI coding agents and RAG stacks fall apart on real-world code because they rely on brittle regex search, static embeddings, or manual sync scripts that constantly drift out of date. A proper index solves three hard problems at once: semantic chunking (what to embed), incremental updates (what to reprocess), and fast similarity search (how to query). CocoIndex packages these into a declarative flow: define sources, transforms, and storage once, then keep your index fresh with a single CLI command. Once your repo is indexed, you get a universal "code context service" that many tools can plug into. Some examples…  ( 10 min )

Deadlock in Operating Systems (OS) What it means in OS Processes (or threads) request resources (mutexes, files, devices, memory pages). A deadlock occurs when processes each hold some resources and wait forever for resources others hold. Simple OS example (classic) Process P1 locks resource A, then tries to lock resource B. Process P2 locks resource B, then tries to lock resource A. Both block waiting for the other → deadlock. Detection (OS) Build a resource-allocation graph or wait-for graph and detect cycles. Cycle detection via DFS. If cycle exists → deadlock. Complexity: graph traversal O(V+E). Prevention & Avoidance (OS) Prevention: disallow one Coffman condition (e.g., enforce ordering of resource acquisition, or disallow hold-and-wait by forcing processes to request all resources…  ( 7 min )

A dev resume isn't just a list - it's a context + impact sales doc. After reviewing more than 25 developer resumes (mobile, backend, fullstack, career changers, etc.), the same 3 mistakes kept showing up. The most common error: the whole resume is written like this: "Development and maintenance of applications..." "Worked on bug fixes and new features..." "Responsible for system X..." That says nothing about: the size of the problem, how hard what you did was, the impact on the product or business. Recruiters read this all day. It turns into noise. Fix: turn each bullet into technical action + what + how + metric/scale Another classic: a beautiful resume full of columns, icons, colors, emojis, and creative UX... and completely indigestible for someone who needs to read fast (or for an ATS). Lots of people fell into these: Multi-column layout, heavy sidebar, icon, emoji in dates, cluttered header Inconsistent dates and sections ("Aug 24", "08/2024", "2024 - present") Important sections missing or weak: Projects, poorly separated Skills, giant text blocks Fix: One column only FAANG LaTeX template Saw this a lot: giant skills list (Java 8 years, Docker, Kubernetes, AWS, Flutter, React...) without showing it once in roles technologies only in the "Skills" section, zero proof in experience or projects missing basic dev keywords: Git, testing, CI/CD, REST API, cloud, even for people who clearly use them daily career in infra/support or teaching, but resume saying "full-stack dev" without a real project/product described Fix: Only list tech you can defend in an interview and tie each one to a role or project.  ( 6 min )

Trying to understand JavaScript closures? ⭐ 1. The Backpack Analogy You pack a backpack at home. That’s basically a closure — a function carrying variables even after the parent function is done. ⭐ 2. The Waiter Analogy You tell a waiter your order: table number, dish, special instructions. That memory he carries along → that’s a closure. ⭐ 3. The Note From a Parent A parent gives their child a secret note. The note = the variables preserved by a closure. ⭐ 4. The Security Guard Analogy A boss gives a guard a list of allowed people and then goes on vacation. The guard remembering the list = closure. ⭐ 5. The Recipe Book A chef hands you a recipe book and closes his restaurant. That recipe book is exactly what a closure feels like. ⭐ 6. The Spare Key Someone gives you a key before moving abroad. The key you keep is the closure’s stored variable. ⭐ 7. The Childhood Tattoo Something meaningful happens when you’re young — and it stays with you forever. That tattoo = a closure holding on to past variables. 🎯 Quick takeaway A closure is simply a tiny bundle of memory that a function takes along with it, even after the place where that memory was created no longer exists.  ( 7 min )

In just a few clicks or commands, you'll have a running service with ECS Express Mode configures infrastructure for you that normally takes ✔️ An Application Load Balancer (ALB) ✔️ CloudWatch Logs ✔️ IAM Roles ✔️ VPC, subnets, and security ✔️ Autoscaling Very little. Just: The container image Service port (if not using the standard one) Any environment variables or secrets (if needed) Optionally, CPU and memory Everything else can remain automatic. Yes. If you already have experience, you can modify: Existing VPC and subnets Security group Log group name Container startup command Health checks Resource limits Scaling configuration But if you're just starting out, it's best to leave everything in Because it lets you focus on what matters: your application. Learning cloud often means dealing with networks, permissions, security, Learning containers Practicing deployments on AWS Creating a project for university Building an MVP or prototype Preparing for cloud certifications You can focus on the workflow without getting lost in advanced details. Although very practical, keep in mind: The ALB has a cost; if you create several services, each one may generate its own load balancer. If you need a complex architecture, Express Mode might fall short. It's perfect for getting started, but large projects may require more advanced ECS configuration.

Disabling local user accounts on all domain‑joined client computers via Group Policy is a valuable security practice. It ensures users only log in with domain accounts, preventing the risks associated with unmanaged local accounts, such as weak or shared passwords. Local accounts can be security risks if passwords are weak or shared among users. Domain accounts allow centralized control and auditing, improving security. Disabling local accounts centrally via Group Policy (GPO) avoids manual configuration on each machine, ensuring uniform policy enforcement. You must have an Active Directory domain with Windows Server 2016, 2019, or 2022 and domain-joined Windows 10/11 clients.

I came across a post from ArkType recently: Regex patterns being parsed at compile time! TypeScript inferring exact string literals like "ac" | "abc" from the pattern "^ab?c$". Not just string, but the actual possible matches. That got me curious. Regex has always been a runtime thing, you write a pattern, match strings against it, and the type system just sees string everywhere. But this was doing it all at compile time. I wanted to understand how, so I decided to build a minimal version myself. ArkType Regex is a compile-time regex parser written entirely in TypeScript's type system. Instead of just validating that a string might match a regex at runtime, it infers the exact string literal types that a regex can produce. For example: // Traditional regex: gives you `string` const match …  ( 14 min )

A lot of people say that “real backend performance” only comes from using Go, Rust, or Python. JavaScript and TypeScript often get labeled as frontend only languages. Here are five reasons why you don’t really need to abandon JavaScript or TypeScript for backend work. Bun is unbelievably quick. It starts fast, handles requests efficiently, and comes with tooling that feels smooth to use. Your frontend uses JS, your backend uses TS, your tests and tooling use the same language too. npm is basically a giant supermarket of libraries. Whatever you need, it’s probably there already. ElysiaJS and Hono are simple, fast, and don’t bring a bunch of unnecessary features you’ll never use. TypeScript gives you great type safety and confidence while coding. There’s a great explanation in this video that breaks everything down really well. https://www.youtube.com/watch?v=DpDHPoStZZ8  ( 7 min )

No copying and pasting 40-character strings. No "wait, which key was for which account?" Within seconds, I was authenticated: You are now logged in as arn:aws:iam:::user/your-user Credentials stored for profile 'default' Step 4: Verify It Worked aws sts get-caller-identity It worked. No access keys in sight. Just clean, secure, temporary tokens doing their job. What Makes This Better? They expire in hours, not years, They auto-rotate every 15 minutes You can check the expiration yourself cat ~/.aws/cli/cache/*.json You'll see something like: { "Credentials": { "AccessKeyId": "...", "SecretAccessKey": "...", "SessionToken": "...", "Expiration": "2025-01-01T12:34:56Z" } } The Bottom Line The entire migration took me 5 minutes. five minutes to eliminate one of the biggest security headaches in cloud development. If you're still using long-term access keys in 2025, this is your sign: Update your CLI to v2.22+ Delete those credentials Run aws login Your security team will thank you. Your future self will thank you. And honestly? It just feels better knowing those permanent keys aren't sitting there anymore.  ( 7 min )

Exception Handling What is an Exception? An exception is an error that occurs during the execution of a program.

If you were building web applications during the first dot-com boom, chances are you wrote Perl. And if you’re now a CTO, tech lead, or senior architect, you may instinctively steer teams away from it—even if you can’t quite explain why. This reflexive aversion isn’t just a preference. It’s what I call Dotcom Survivor Syndrome : a long-standing bias formed by the messy, experimental, high-pressure environment of the early web, where Perl was both a lifeline and a liability. Perl wasn’t the problem. The conditions under which we used it were. And unfortunately, those conditions, combined with a separate, prolonged misstep over versioning, continue to distort Perl’s reputation to this day. The Glory Days: Perl at the Heart of the Early Web In the mid- to late-1990s, Perl was the web’s duct…  ( 9 min )

The Architecture of Inevitability We've been sold a myth about self-discipline. It’s a story of grit, of white-knuckled willpower, of forcing yourself to do the hard thing through sheer mental brute force. This is a losing strategy. It treats the human mind like a flawed machine to be whipped into submission. It’s exhausting, and it rarely works long-term. True mastery of self and time isn't about becoming a better taskmaster. It’s about becoming a better architect. It's about designing a system—an environment, a set of rules, a protocol for energy—where the desired outcome is not just possible, but inevitable. You don't need more discipline; you need a better system. The Operating System: Three Core Principles Every effective system runs on a clear set of principles. For personal mastery,…  ( 9 min )

If you’ve played with AI chatbots or agentic frameworks lately, you’ve probably had the same moment I had - most agents can plan, reason, call tools, run workflows… yet somehow they can’t remember something you said 10 minutes ago. It’s impressive and frustrating at the same time. That gap — between advanced reasoning and almost no memory — is quickly becoming one of the biggest things holding AI agents back from feeling genuinely helpful. The Real Bottleneck Isn’t the Model. It’s the Memory. Most AI chat systems implemented today still live inside the model’s context window. Whatever fits in the prompt is what the agent “knows,” and the moment you step outside that window, it’s gone. That creates familiar issues: You keep repeating yourself The agent forgets your preferences Every new r…  ( 8 min )

Type constraints in Terraform play a crucial role in writing predictable, reusable, and maintainable infrastructure-as-code. When working with AWS resources, ensuring that your variables are properly typed helps prevent configuration errors, enforces standards, and makes your modules easier to understand and more robust. This post explains Terraform’s type system in depth and demonstrates how these type constraints apply to AWS infrastructure deployments. Terraform uses type constraints to ensure that variables receive values in the correct format. Without proper typing, it becomes easy to pass the wrong kind of data into your AWS resources, leading to failed deployments or hidden configuration issues. Types also help teams maintain consistency, validate expectations, and build self-docume…  ( 8 min )

Untouchable: The Future of Robotics is Magnetic Tired of robots limited by clumsy grippers and delicate surfaces getting scratched? Imagine a world where machines can manipulate objects with precision, without ever making contact. We're on the cusp of a revolution in robotics, moving beyond physical interaction to master the art of non-contact manipulation. The key is leveraging magnetic fields to levitate and control objects in 3D space. By precisely orchestrating a network of electromagnets, we can create a "magnetic hand" capable of moving, rotating, and positioning items with incredible accuracy. Complex control algorithms, trained using deep reinforcement learning, manage the electromagnetic forces to achieve stable and predictable movements. Think of it like playing a 3D chess game…  ( 7 min )

Epic CEO Tim Sweeney Urges Steam: Remove 'Made with AI' Game Tags\n\nSteam, a dominant PC gaming platform, recently introduced \"Made with AI\" tags for games to provide transparency to players regarding the use of generative AI in game development. This move was intended to help consumers make informed choices and navigate the evolving landscape of AI-powered content creation, especially given ongoing discussions about intellectual property and ethics in AI. Publishers are required to disclose if their games use AI to generate assets, code, or other elements, categorizing AI use into pre-generated or live-generated content.\n\nHowever, Epic Games CEO Tim Sweeney has publicly urged Steam to reconsider and remove these \"Made with AI\" tags.

💡 Quick Take: The traditional full-stack roadmap is obsolete in the age of AI. To thrive, developers must adopt the 'Architect & The Automaton' model, focusing on system design and high-level direction while leveraging AI for implementation. The full-stack roadmap you've been memorizing is a map to a city that no longer exists. Learn HTML, then CSS, then JavaScript, then React, then Node.js, then a database, then Docker. It was a reliable, linear path. It created specialists in predictable stacks. That era is over. AI is not another framework to learn. It’s a tectonic shift that has fundamentally changed the landscape. Treating tools like GPT-4 or GitHub Copilot as mere productivity boosters is like seeing the first automobile and thinking, "What a nice, fast horse." You're missing the p…  ( 9 min )

Seeing Google's Doodle tribute to Pac-Man recently sent me spiraling down a nostalgia rabbit hole. It reminded me of a MOOC I took in what now feels like ancient history—a Gemini search of my old Gmail archives confirms it was UC Berkeley CS 188: Introduction to Artificial Intelligence via EdX, probably around 2012. The year 2012. The year Obama won re-election, the Mayan calendar "ended," and Honey Boo Boo was somehow a cultural phenomenon. Siri was barely a year old—helping sell iPhones like hotcakes despite rarely understanding what you asked. "Deep learning" was a phrase you'd find only in academic papers, not headlines.

Introduction Hello 👋, In this article I will present my opinions on Vibe Coding. In the last 2 years the term "AI Vibe Coding" has been very hyped. I mean the idea of "Clicking a button and generating anything you can imagine" is very exciting at first but not a great idea at the same time. I will give my opinion on why it isn't a good idea to depend on AI Vibe Coding tools. Let's first talk about how basically these Vibe Coding AI Models work. AI LLMs are trained on data and are trained to predict output from user input (prompt) based on that data. Which means AI Models that can code is trained on existing human written code and AI Models that can draw is trained on existing human drawn art. This means that AI can't create something entirely unique that has never been created by humans…  ( 8 min )

Hey everyone! AI-powered website security scanner designed to help developers and teams catch vulnerabilities before hackers do. It’s still early, rough around the edges, and absolutely an MVP… The MVP scans a website URL and uses AI + rule-based checks to flag: Common vulnerabilities (misconfigurations, exposed endpoints, weak headers) Potential security risks in publicly reachable pages Missing or unsafe security headers Basic performance & implementation issues that relate to security The idea is simple: give developers fast, actionable insights without needing to be a security expert. I’d love feedback from anyone in the dev → deploy pipeline: ✔️ Web developers ✔️ QA testers ✔️ Project managers ✔️ Security engineers / pentesters If you build or ship websites, this tool should feel immediately useful — or at least interesting enough to poke holes in. Security often becomes an afterthought — not because developers don’t care, Scanners are expensive OWASP tools feel intimidating Manual reviews are slow Teams don’t have dedicated security folks So the goal with this MVP is to make security checks accessible, fast, and AI-assisted. This is version 0.1 — tons of improvements planned: Deeper OWASP coverage Better AI reasoning (multiple agents) Exportable reports API access for CI/CD Scheduled scans Chrome extension for quick checks Team dashboards + history logs If enough devs find value here, I’ll double down on building it out. 👉 WebGuard Please break it.

Yesterday, I noticed something alarming in Mukbang 3D: regular users signing in with Google were being asked to grant access to Google Analytics data and Cloud Platform resources. For an app that just needs your email and name, this is terrible. Here's how a simple developer convenience created a confusing security prompt—and how I tracked it down. Instead of the clean, minimal consent screen users expect ("Mukbang 3D wants to access your email and profile"), they were seeing a wall of intimidating permissions including developer-level scopes like analytics.readonly. Understandably, users were abandoning the sign-in flow entirely. First I checked the mobile app's OAuth configuration. The Client ID looked correct—it only requested email and profile scopes.

The Paradox of Infinite Leverage We were promised a revolution. A suite of AI tools that would grant us 10x leverage, compress timelines, and unleash an unprecedented wave of creation. The tools arrived, yet the revolution feels… muted. Many find themselves busier than ever, caught in a frantic loop of prompt engineering, content generation, and tool-hopping. They are producing more noise, not more signal. This is the great paradox of the AI era: we have access to near-infinite leverage, yet our output remains stubbornly linear. Why?

Introduction When working with Uniface ProcScript, you might encounter mysterious syntax errors that seem to point at perfectly valid code. The culprit could be invisible non-breaking space characters (0xA0) lurking in your source files. This article explains the $ALLOW_NOBREAK_SPACE configuration parameter and how it can help you deal with this common issue. $ALLOW_NOBREAK_SPACE is a configuration parameter in Uniface 10.4 that controls whether non-breaking spaces (hexadecimal value 0xA0) are allowed in ProcScript code. By default, these characters cause syntax errors when the Uniface compiler encounters them. Syntax: $ALLOW_NOBREAK_SPACE = 1 | 0 Values: 1 - Non-breaking spaces (0xA0) are allowed in ProcScript 0 - Non-breaking spaces cause syntax errors Default: None (not set, be…  ( 7 min )

Introduction Recently, I read an article titled "Alias Settings of Engineers Around the World" (in Japanese). As a PostgreSQL engineer, this got me thinking: "If they are customizing their bash aliases, how are they configuring their psql environments?"

Its configuration file is named psqlrc, and it has the following characteristics: System-wide settings: The system-wide psqlrc file is stored in ../etc/ relative to the directory containing the PostgreSQL executable. This directory can be explicitly set using the environment variable PGSYSCONFDIR. User-specific settings…  ( 22 min )

There has never been a stranger moment to be a Computer Science graduate. On one hand, the world is flooded with content telling you that “AI will replace programmers,” “coding is dead,” or “software jobs are disappearing.” On the other hand, every company—from scrappy startups to trillion-dollar giants—is aggressively announcing AI strategies, hiring AI engineers, looking for systems specialists, and expanding their technical teams. This contradiction has left an entire generation asking the same question: Where do I fit in?

Breaking the Sound Barrier with AI: Reinventing Flight Design Imagine designing a supersonic jet engine without a wind tunnel, or optimizing a spacecraft’s heat shield before ever firing it up. The cost and complexity of physical testing have always been a massive bottleneck in aerospace engineering. But what if we could accurately simulate these complex aerodynamic conditions with unprecedented speed and efficiency using AI? The core idea is this: train a neural network to act as a "surrogate" for complex computational fluid dynamics (CFD) simulations. Instead of running computationally intensive calculations every time we tweak a design, we can use the AI to instantly predict the aerodynamic performance. This allows for rapid exploration of design possibilities, something previously im…  ( 7 min )

The popularity of Rust and Go in backend development cannot be overstated. Rust’s emphasis on memory safety and performance makes it ideal for building systems where speed and reliability are paramount. On the…  ( 8 min )

We spent the last two years figuring out how to make LLMs "smart." We learned RAG, Chain-of-Thought, and Tool Use. But in 2025, the challenge isn't intelligence. It's Containment. The difference between a demo and a production system isn't the prompt, it's the architecture that stops the LLM from bankrupting you or crashing your backend. I call this shift "Defensive AI Architecture." It's the discipline of treating LLMs not as magic oracles, but as non-deterministic, hostile microservices. The Anatomy of an AI Crash The Context Overflow: A user pastes a 50-page PDF. A naive sliding window drops the System Prompt (the instructions), lobotomizing the bot mid-conversation.

As engineers, we live and breathe automation. We build CI/CD pipelines to ship code faster, write scripts to provision infrastructure, and create APIs to make data flow seamlessly. So why are so many B2B companies still collecting customer testimonials like it's 2005—with manual emails, calendar invites, and a prayer? Social proof isn't just marketing fluff; it's a critical dataset for building trust and driving growth. But manual collection is a bottleneck. It’s inconsistent, time-consuming, and simply doesn't scale. Let's treat this like any other engineering problem and build a robust, automated pipeline. Manually asking for video testimonials is a high-friction process for everyone: Your Team: It's a logistical nightmare of scheduling, following up, and editing. Your Customer: They…  ( 9 min )

In the gleaming computer labs of Britain's elite independent schools, fifteen-year-olds are learning to prompt AI systems with the sophistication of seasoned engineers. They debate the ethics of machine learning, dissect systemic bias in algorithmic systems, and explore how artificial intelligence might reshape their future careers. Meanwhile, in under-resourced state schools across the country, students encounter AI primarily through basic tools like ChatGPT—if they encounter it at all. This emerging divide in AI literacy threatens to create a new form of educational apartheid, one that could entrench class distinctions more deeply than any previous technological revolution. The concept of literacy has evolved dramatically since the industrial age. What began as simply reading and writing…  ( 28 min )

If you’ve ever built a React application that fetches data from an API, you know the challenges of managing server state. Between loading states, error handling, caching, and synchronization, data management often becomes complex. Enter React Query — the missing piece for data fetching in React applications. In this guide, we’ll explore how React Query transforms your development experience and improves app performance. React Query (now TanStack Query) handles server state management in React applications. It provides hooks for fetching, caching, synchronizing, and updating server data without complex “global state” solutions. Simplified Data Fetching: Dramatically reduce boilerplate code Intelligent Caching: Automatic caching and background updates Built-in Loading & Error States: N…  ( 7 min )

In the world of data management, querying databases efficiently and accurately is a common challenge. Traditionally, accessing information from databases requires knowledge of SQL, a skill that not all users possess. As businesses grow and data becomes more complex, multi-agent systems for text to SQL are emerging as a powerful solution. These systems enable users to interact with databases using natural language, converting text queries into SQL queries automatically. A multi-agent system is a collection of autonomous agents that work collaboratively to solve a complex problem. In the context of text-to-SQL, these agents specialize in different tasks, such as understanding the natural language query, mapping that query to the database schema, and generating the appropriate SQL query. Rath…  ( 9 min )

Software development is full of repeated problems — from creating objects to managing complexity to organizing code. Instead of reinventing the wheel every time, developers rely on design patterns — proven solutions that help keep code simple, flexible, and maintainable. Think of design patterns as reusable templates. They don’t give you exact code to copy-paste, but they guide you toward a clean and reliable way to solve common problems. Below are the patterns every developer should understand, no matter what language you work with. Sometimes you need a single, globally accessible object — like a database connection, logger, or configuration manager. Why it matters: Simple example: Creating objects can become messy when different types require different setup steps. The Factory Method pat…  ( 7 min )

Today in the #30DaysOfAWSTerraform challenge, I finally understood how powerful Terraform variables are and how using them properly makes your code cleaner, more organized, less repetitive, and easier to maintain. This was the day things started clicking for me. Here’s what I personally understood during Day 5: Variables remove repetition and make code more organized and readable. I learned input variables, output variables, and local values. I understood how to view resource IDs using terraform output. I learned how to override variables using: terraform.tfvars command-line overrides (terraform plan -var=environment=test) environment variables ($env:TF_VAR_environment="test") Overall, variables make code flexible and eliminate hardcoding everywhere. These are the exact commands I ran whil…  ( 7 min )

Your traffic dropped 40% overnight. You checked Google Search Console. Then checked again. Refreshed the analytics dashboard three times because surely the data was wrong. It wasn't.

SQL (Structured Query Language) is the backbone of data analysis, enabling us to extract, manipulate, and analyze data stored in relational databases. As I revisit the basics of SQL and move into more complex queries, I have realized just how powerful advanced SQL can be for uncovering deeper insights. It is essential for anyone looking to level up their data analysis skills to master SQL. Here are some of the advanced SQL concepts that helped me elevate my queries: JOIN Types (INNER, LEFT, RIGHT, FULL OUTER): Understanding the different types of joins is key when working with multiple tables. INNER JOINs bring rows with matching values, while LEFT/RIGHT JOINs include all records from one table, filling with NULLs where there is no match. FULL OUTER JOINs combine both sides. Subqueries a…  ( 8 min )

Before Kiro, I saw AI as just another tool. After building Cadaver's Crypt, I see it as a development partner that understands context, domain knowledge, and creative vision. From: Linear coding with constant context switching To: Conversational development with integrated domain expertise Kiro didn't just help me write code - it helped me think through complex problems in medical education and find innovative solutions. When Kiro generated a complete Three.js anatomy viewer with built-in medical validation and Halloween effects in one conversation, I realized this was different. The platform understood: Medical accuracy requirements Educational psychology principles 3D graphics optimization Theme consistency needs The real value came from Kiro's ability to: Maintain context across multiple development sessions Suggest architectural improvements I hadn't considered Automate validation workflows that would have taken weeks Balance educational integrity with user engagement A production-ready medical education platform built in record time, with features that would typically require a full team of developers and medical experts. edtech #medtech #ai #webdev #innovation kiro  ( 6 min )

The Problem In our car mechanic CRM application, users needed to search across multiple entities simultaneously—customers, their vehicles, appointment history, and service records. However, our data architecture presented a significant challenge. Our application followed database normalization best practices. Data was organized into separate collections: Users collection - Customer information Appointments collection - Service appointment records Vehicles collection - Vehicle details with references to master data collections While this normalized structure kept our data clean and avoided redundancy, it created a performance bottleneck for search operations. To execute a single search query, we needed to perform 2-3 layers of lookups across collections, followed by text regexp searches. …  ( 9 min )

Waste management typically depends on fixed schedules. Drivers follow the same routine every day, even if bins are half-empty. This wastes time, fuel, and effort. GreenGuardian uses artificial intelligence to change this pattern by introducing dynamic waste monitoring and predictive planning. The system collects data from smart bins, drivers, resident requests, and historical waste patterns. AI models then analyze this information to detect waste hotspots, peak usage times, and unusual surges. This is especially useful during events like Bakra Eid, when organic waste increases sharply in certain areas. Route optimization is one of the key AI-powered features. Instead of sending drivers on predefined routes, the system creates routes based on actual bin fill levels, road layout, driver availability, and current workload. This reduces unnecessary travel, lowers emissions, and shortens collection time. Another intelligent feature is the sentiment analysis engine. Residents often express concerns or complaints through the mobile app. These messages are processed to understand their tone and categorize issues. This helps society administrators respond faster and identify repeated problems without manually reading every message. AI doesn’t replace human workers — it strengthens them. By giving accurate predictions, smarter planning, and meaningful insights, it allows staff to focus on execution rather than guesswork. As more data accumulates, the system continually improves its recommendations, making waste management smoother and more efficient over time.  ( 6 min )

We are thrilled to announce that echo3D now has a plugin for Autodesk 3ds Max. For decades, Autodesk 3ds Max has been the gold standard for 3D modeling, animation, and rendering. Now, by integrating directly with echo3D’s robust 3D Digital Asset Management (DAM) platform, we are closing the gap between creation and deployment. This integration allows 3D designers and teams at large organizations to stream 3D assets directly from the 3ds Max interface into the echo3D DAM, completely eliminating the friction of manual exports, uploads, and file juggling.

The reality? 90% of it was repetitive clickbait or shallow press releases. I realized I was spending an hour just trying to find something to read, rather than actually reading. I decided to engineer my way out of this loop. I didn't just want a GPT wrapper that summarizes text.

Not long enough to call myself a senior, but long enough to have worked alongside brilliant engineers who've been doing this for a decade or more. And you know what I've noticed? That faraway look in their eyes during sprint planning. That wistful tone when someone mentions "work-life balance" like it's a mythical creature. These poems aren't born from my own ten years of experience - I'm not there yet.

I remember the day clearly. After returning from KubeCon in 2022, I was curious about local AWS activity and decided to search for user groups near me. I found a meetup listed for Vadodara and went — not as a speaker, not as an organiser, simply as someone who wanted to learn. Walking into that room for the first time was a small shock. People were talking architecture, deployments, and product announcements like it was just another day. I felt out of place for a moment. Then Manan Vasavada — hosting the meetup at Avdevs — said something simple and disarming: “No one here is an expert. You have a topic? Just talk about it.” That sentence changed everything.

AI code generators write more code than ever, and they do it fast. Sahil Lavingia said it well in a recent tweet. If developers now produce five to ten times more code with AI, we need something that can review five to ten times more code too. That is the real problem. Tools like Cursor generate code that looks right but often contains small mistakes that only show up when the project runs. Wrong Prisma fields, missing checks, loose validation, repeated logic, or scripts that fail silently. None of this feels dramatic. It is just enough to slow you down or break production.

GitHub Home I still vividly remember that Friday midnight. I, a man in my forties who should have been at home enjoying the weekend, was instead in a cold server room, the hum of fans buzzing in my ears, and a stream of error logs scrolling endlessly on the terminal before me. What was supposed to be a "simple" version update had turned into a disaster. The service wouldn't start, the rollback script failed, and on the other end of the phone was the furious roar of a client. At that moment, staring at the screen, I had only one thought: "There has to be a better way." We old-timers grew up in an era when the term "maintenance window" was a fact of life.

Note: This article contains affiliate links. I only recommend hardware I actually use. If you are a student starting your cybersecurity journey, you have probably Googled “Best WiFi Adapter for Kali Linux.” And you probably saw thousands of old forum posts recommending the TP-Link TL-WN722N. Do not buy it. Here is the trap that catches 90% of beginners: Version 1 of that adapter was legendary. It used the Atheros AR9271 chipset. Version 2 and Version 3 (which is what Amazon sells now) swapped the chipset to the Realtek RTL8188EUS. Why does this matter? does not support Monitor Mode or Packet Injection native to Linux. If you buy it, you will spend 3 days fighting with GitHub driver patches, kernel crashes, and errors. It is a nightmare. I stopped fighting with old adapters and switched to the Alfa AWUS036ACS. After testing it for a month, here is why it is the only budget adapter I recommend for students: It runs on the Realtek RTL8811AU chipset. Unlike the TP-Link, the drivers for this are stable in the Kali Linux repository. You install them once, and it works forever: sudo apt install realtek-rtl88xxau-dkms Old adapters (like the Alfa NHA) are single-band (2.4GHz only). 5GHz (AC). It usually costs around $25 — $30. Stop trying to make the TP-Link work. It’s not 2016 anymore. If you want to plug it in, run airmon-ng, and start capturing handshakes immediately, get the Alfa.

I'm organizing a Creative Challenge where participants will: Create a track using ONLY OBSIDIAN Neural Record the entire process live (OBS Studio) Max 2 minutes per track At least one sound must be generated using the Draw Canvas feature (yeah, you can literally draw your audio) 1st place: 1 year free subscription 2nd place: 6 months free 3rd place: 3 months free All participants: bonus credits Limited to ~20 participants (first come, first served when I officially launch it) Still in planning phase! I'm working out: Final rules & timeline (probably 3 weeks to create) Judging process (jury + community vote) Technical requirements If you're interested in joining when this launches: Create an account at obsidian-neural.com You'll need a DAW (Bitwig, Ableton, Reaper, etc.) to run the VST3 plugin The core plugin is free and open-source on GitHub Cloud inference is optional (paid tiers available, but free tier exists) OBSIDIAN Neural isn't just another "type prompt, get music" tool. It's a multi-track sampler that integrates into your actual production workflow: Generate loops, textures, and sounds from text or drawings Real-time integration with your DAW Local + cloud inference options Presented at AES AIMLA 2025 in London The Draw Canvas feature is particularly fun - you literally sketch on a canvas and it generates audio based on your drawing + keywords. Perfect for this kind of creative challenge. Since this is still in planning: Would you be interested in participating? What would make this challenge more appealing? Any suggestions on rules/format? I'll post an official announcement once everything is finalized, but wanted to give the DEV community a heads-up first. Drop a comment if you're interested or have ideas!  ( 7 min )

Question 1: You have launched an EC2 instance that will host a NodeJS application. After installing all the required software and configured your application, you noted down the EC2 instance public IPv4 so you can access it. Then, you stopped and then started your EC2 instance to complete the application configuration. After restart, you can't access the EC2 instance, and you found that the EC2 instance public IPv4 has been changed. What should you do to assign a fixed public IPv4 to your EC2 instance? Correct Answer: (1) Allocating an Elastic IP provides a static public IPv4 address that remains associated with your EC2 instance, even when it is stopped and restarted, ensuring uninterrupted access to your application. This approach is important for maintaining reliable connectivity wit…  ( 7 min )

JavaScript runs synchronously. The Event Loop enables efficient management of asynchronous operations, providing non-blocking code execution. Understanding how the Event Loop, the call stack, the task queue, and the microtask queue work helps developers write more efficient and responsive web applications. The Event Loop is a mechanism in JavaScript that allows asynchronous processing of events and tasks, ensuring non-blocking code execution. This is especially important for web applications, where the user interface must remain responsive even when long-running operations are performed. Call Stack: This is a data structure that keeps information about the currently executing function calls. When a function is called, it is pushed onto the stack, and when it finishes execution, it is poppe…  ( 7 min )

As AI systems like ChatGPT, Gemini, Perplexity, and Copilot continue to reshape how users find information, brands must adapt to a world where visibility depends on being included in AI-generated answers, not just traditional search results. AI engines give single, definitive responses — meaning only a handful of brands appear at the top of every query. To stay competitive, businesses rely on AI ranking analyzer tools. These platforms evaluate how often your brand appears inside answers generated by leading AI models, identify the phrases associated with your business, and highlight gaps where competitors perform better. Below are three powerful AI ranking analyzer tools — starting with the most complete solution on the market. AI Rank Checker stands out as the most comprehensive tool for …  ( 8 min )

As AI search engines like ChatGPT, Gemini, Perplexity, Grok, and Microsoft Copilot become the primary way people discover brands, AI brand visibility has become one of the most important metrics in digital marketing. Unlike traditional search engines that display multiple pages of results, AI assistants typically give one answer — and only a few brands are included. To help companies understand where they stand, a new class of platforms has emerged: AI brand visibility tools. These tools show how frequently a brand appears in AI-generated responses, how it's described, and what can be done to improve presence across different AI systems. Below are three of the best AI brand visibility tools today, led by the only platform designed specifically for both AI tracking and optimization. AI Rank…  ( 8 min )

Large Language Models (LLMs) like Claude possess incredible reasoning capabilities, but they suffer from a critical flaw: They have no object permanence. Once you close a chat session, the "mind" is wiped. While features like "Projects" or huge context windows (200k+ tokens) help, they are temporary buffers, not true memory. They are expensive, slow to re-process, and don't persist across different interfaces (e.g., moving from VS Code to the web interface). To move from Chatbots to true Agents, we need to solve the state problem. The Model Context Protocol (MCP) is often described as a way to "connect AI to tools." But theoretically, it allows us to decouple the reasoning engine (the LLM) from the state (the data). Instead of trying to cram everything into the prompt (Context Stuffing), w…  ( 10 min )

Hey Indie Hackers 👋 It’s called pngtowebp.io, and it converts PNG images into WebP directly in the browser. No uploads, no accounts, no nonsense. Why I built it PNG files were slowing everything down. Lighthouse kept yelling at me. I know the solution was WebP, but most tools online were: Too slow Full of ads Required uploading files Hidden behind paywalls Or had weird usage limits I just wanted something fast, free, and private. So I built it myself. What the tool actually does Not much, honestly — and that’s the whole point. You upload PNG → it gives you WebP. The entire conversion happens locally in your browser, using: His tool is very easy to use — you just need to upload your PNG file, and it will generate a WebP file for you. It’s extremely fast and convenient. pngtowebp.io If you use it and something breaks, or if you have an idea to make it better, I’d genuinely love to hear from you.

Interface compliance checks in Go let you verify at compile-time that your types actually implement the interfaces they claim to, preventing runtime disasters.

Here's the thing: most marketing teams aren't bad at budgeting because they're careless. They're bad at it because they're optimistic. That Facebook campaign that "performed well"? Define well. That content initiative that "built brand awareness"? Cool, cool—how much brand awareness costs per unit, exactly? I've audited enough marketing budgets to know the pattern. Roughly 20-30% of annual spend goes to things that either don't work anymore, never worked, or nobody can actually remember approving.

Originally published on Entropic Drift Over the past few weeks, I've been migrating Prodigy—my Rust-based AI workflow orchestration tool—to use functional programming patterns from Stillwater, a library I built for applicative validation and effect handling in Rust.

Not every change was revolutionary, but three patterns produced outsized benefits in testability, safety, and code clarity. This post breaks down each one with concrete before/after comparisons. The Problem: Prodigy's MapReduce workflows aggregate results from parallel AI agents.

Pre-compiled Neovim binaries fail on OpenWrt with interpreter/linker errors: ei https://github.com/neovim/neovim/releases/download/nightly/nvim-linux-x86_64.tar.gz nvim # Error: Failed to execute process: The file exists and is executable. # Check the interpreter or linker? This happens due to glibc/musl incompatibility. Building from source ensures compatibility with OpenWrt's musl libc. This guide uses OpenWrt 24.10.4 x86_64. For other versions, refer to the original guide. Install the required build tools and libraries: opkg update opkg install git git-http python3 python3-pip make luajit gcc coreutils-install pip install cmake OpenWrt's minimal environment lacks some standard libraries that Neovim expects. The dynamic linker library is built into musl but needs a stub for linking: printf "!\n" > /usr/lib/libdl.a This creates an empty archive that satisfies the linker without adding actual code (musl already provides dlopen and friends). Create a dummy shared library for the utility functions: echo "int main() { return 0; }" > dummy.c gcc -shared -o /usr/lib/libutil.so dummy.c rm dummy.c Most libutil functions (like forkpty) are either unused by Neovim or provided by other libraries on musl systems. Clone the repository (shallow clone to save space): git clone https://github.com/neovim/neovim --depth=1 cd neovim Build with release optimizations and debug symbols: make CMAKE_BUILD_TYPE=RelWithDebInfo This takes 10-30 minutes depending on your system. The RelWithDebInfo build type provides good performance while keeping some debug information for troubleshooting. Install to the default location: make install This installs to /usr/local/bin/nvim.

GitHub Home A hacker exploited this vulnerability, bypassed authentication, and stole the entire user table data. By the time we discovered it, it was too late. For the next few months, our entire team lived in nightmares: cooperating with investigations, appeasing clients, fixing vulnerabilities, checking all company projects for similar risks... The company's reputation and business suffered heavy damage. That incident taught me the most profound lesson: in the world of web development, security always comes first. Many developers, especially when project deadlines are tight, view "security" as a "feature module." They say: "Let's implement the main functionality first, and we'll 'add' security features in the next iteration." This is a fatal misunderstanding. Security is not a coat of p…  ( 9 min )

Let’s be honest, most insurance software looks like it was built when Nokia phones were “cutting edge.” Guidewire saw this too. Enter JDP — the Jutro Digital Platform. A framework? Yes. All of the above. If React is a kitchen, JDP is the fully-loaded restaurant where the stove, the recipes, the ingredients, and the waitstaff already know what they’re doing. Let’s break it down. So… what exactly IS JDP? JDP is Guidewire’s all-in-one platform for building, running, styling, and shipping modern insurance web apps — powered by React and the Jutro Design System. Why does JDP even exist? Because building enterprise insurance apps is not the same as building to-do lists.

It just... happened naturally as I figured things out. Every project I build starts the same way.A blank Python file and an idea. No UI. No database. No structure. Just me trying to make the core idea work. This stage is messy. Lots of print statements everywhere. Lots of "wait, why isn't this working?" Once I get the basic functionality down.Like, the thing actually does what it's supposed to do.I start thinking: "Okay... but where do I save this?" And that's when I move to the next part.

Introduction: The Shift in Audio Engineering The domain of digital signal processing (DSP) has historically presented significant barriers to entry. Tasks such as isolating a specific instrument from a mixed audio file were once considered technically impossible—often compared to "unbaking a cake" to retrieve the eggs and flour. However, the advent of machine learning models trained on spectral data has fundamentally altered this landscape. Before discussing the workflow, it is essential to understand the technology behind "unmixing." Modern source separation relies on deep neural networks (DNNs) that analyze the spectrogram of an audio file. These networks are trained to recognize the specific frequency footprints and harmonic structures of different sound sources. The first application…  ( 8 min )

(For individual use, please see GPTLocalhost.) Recent findings show that 77% of workers disclose confidential business information via ChatGPT and other cloud AI platforms, posing significant security and compliance challenges. Given Microsoft Word’s status as a widely used word processor, it’s not surprising that some workers might transfer sensitive information to these external AI services by copying and pasting. In light of these concerns, organizations are increasingly turning to on-premise Large Language Models (LLMs) to safeguard sensitive data and ensure regulatory compliance. By hosting LLMs internally, businesses can exert greater control over their information environments, reducing the risk of unauthorized access or data breaches associated with external cloud services. For legal professionals, the implications of these findings are particularly significant. Addressing security concerns, they now have an effective solution available: the IBM Granite 4 series models for contract analysis seamlessly integrated into Microsoft Word. This integration is enabled through a local Word Add-in named LocPilot, which brings local LLMs to Microsoft Word. With LocPilot, your team can run powerful LLMs directly on their computers or an Intranet server — eliminating the need for cloud services and monthly fees while ensuring complete privacy. You can effortlessly switch between models and work more efficiently, all within a local environment. Here’s a quick demo: We hope this demonstration opens up new avenues for thought and inspires you to develop additional use cases that empower your team with the latest on-premise AI. If you have any specific ideas or suggestions, please don’t hesitate to contact us at info@locpilot.com. Our mission is to make local AI more accessible and affordable for all teams.  ( 7 min )

In my previous blog post, I covered the fundamentals of PL/SQL collections, focusing on the different types: Associative Arrays, Nested Tables, and VARRAYs. While there’s much more to explore about collections, in this post, I’ll focus on two important collection methods: DELETE and TRIM. Collection Methods They are called methods because they use member method syntax, unlike functions or procedures, which require passing collections as parameters. The syntax is similar to other programming languages, such as JavaScript. For example: COUNT function: Returns the current number of elements in a collection. Wrong Syntax COUNT(book_table) Correct syntax book_table.COUNT Note that collection methods are available only in PL/SQL, not within SQL. While I’m not listing and explaining all the collection methods, let’s focus on DELETE and TRIM, as they have interesting behaviors we should know. DELETE Method DELETE (without any arguments) DELETE(i) Removes the i-th element from a nested table or associative array. DELTE(i, j) Removes all elements in an inclusive range starting from i and ending at j. Important Note: When you use parameters with DELETE, a placeholder is kept for the “removed” element. TRIM Method Do Not Use DELETE and TRIM on the Same Collection PL/SQL offers powerful and useful methods, but it’s important to pay close attention to how each one is used.  ( 7 min )

Background Current Business Retreats Are you familiar with business retreats? These are intensive study camps or employee trips with a focus on relaxation, organized for companies operating primarily in a near-full remote work mode. Typically held about once every six months, they target companies that allow remote work, especially tech companies. The specific way a retreat is conducted varies from organization to organization, but one common aspect is that members must always spend time together. Usually, some curriculum is planned, and everyone gathers in a room for workshops, or even during free time, there is pressure to interact, converse, and engage in discussions with other members.

Unlocking AI's Universal Secrets: Do Neural Networks Think in Fractals? Imagine training an AI to recognize cats. It excels with close-up photos, but fails miserably when shown a distant, pixelated feline. This exposes a fundamental challenge: how can we build AI systems that generalize across different scales and perspectives? The answer might lie in a hidden mathematical structure spontaneously emerging within neural networks: Kolmogorov-Arnold Geometry. At its core, Kolmogorov-Arnold Geometry describes a way to represent complex functions as compositions of simpler functions. Think of it like breaking down a complicated painting into a series of simpler brushstrokes at different magnifications. The fascinating discovery is that neural networks seem to learn this geometric structure on…  ( 7 min )

For years, tech leaders have repeated the same line: “Data is the new oil.” And they’re right, data powers AI the way oil powered the industrial revolution.

I recently baked a football cake and it helped me realize AI agents work just like layered desserts. Here’s how flavors, molds and icing maps to agentic design. The code example below is designed to break down user goals into actionable steps and execute them using either custom tools or LLM reasoning. It uses regex to extract numbered steps from the LLM’s plan output. Executes each step by matching keywords like "search" or "compute" to the appropriate tool, or falls back to LLM reasoning. Just like a custom cake has layers of flavor, structure, and decoration, an AI agent has its own stack. It uses llama 3 LLM model and created two custom simple tools: search_tool() - simulates a search engine returning mock results. compute_tool() - simulates a computation task returning a placeholder…  ( 11 min )

It’s mathematical teleportation. A secret told only to yourself = a unary key (private universe) A secret told BETWEEN identities = a binary key (shared universe) And the moment we said: secret “secret@withwhom” We invented the algebraic rule for shared secret derivation. Unary vs Binary Secrets Unary secret (private channel) me.wallet.secret("alpha") This produces a 1-arity universe: U(alpha) → only ME can derive it Because the keyspace derives only from: secret + path + local identity So only you can decrypt the blob under: 🔗 2. Binary secret = shared universe me.wallet.secret("alpha@pamela") This is fundamentally: U(alpha@pamela) = intersection( ME_identity , Pamela_identity ) A 2-identity shared space. So: It creates what cryptographers call: A Multi-party Semantic Channel.  ( 6 min )

“You should live your life like a lion which means that most of your time you’re resting, lazing around, doing whatever you find entertaining, and then once in a while, you get obsessed with something and you just pour everything into it.” - Naval Ravikant Last year, I completed my Masters in Australia. Two paths lay ahead: accept a comfortable job with visa security, or build something that could create real impact. This philosophy captured my journey with Nexus Beings. For a long time, the concept lived quietly in notes and sketches while I navigated life as an international student. Then came the obsession: building digital agents that don't just respond, but understand; systems that bring context, emotion, and intent to the world of service. I chose to build. Today, Nexus Beings has achieved proof of concept. Bootstrapping as an immigrant meant every decision carried extra weight. Without external funding or a safety net, every line of code, every experiment, and every pivot had to matter. These constraints became my greatest teacher, fostering innovation through limitation and patience through uncertainty. This milestone represents more than technical validation. It proves that conviction outlasts complexity and that clarity of purpose sustains when traditional resources cannot. While Nexus Beings continues to evolve, our foundation stands strong: intelligent real-time conversational video agents that deliver warmth, reliability, and empathy to service environments. What began as an experiment is steadily advancing toward redefining digital presence in customer experience. The comfortable job would have been easier. But building technology that transforms how businesses connect with customers? That obsession was worth every risk. The journey continues, grounded in purpose and guided by the belief in what's next.  ( 8 min )

Faith that unlocks righteousness. Romans 4 is not just Paul teaching theology. It’s Paul pulling back the veil on how God has always worked with humanity. Long before Scripture developed its structure, long before Israel became a nation, long before there was a temple, a priesthood, or religious tradition, God revealed something far more foundational: Righteousness has always been a matter of the heart. Everything else is commentary. In Romans 4, Paul is not introducing a new idea—he’s reminding the church of something ancient, something older than Moses, older than Jacob, older even than circumcision: the righteousness that comes through believing God simply because He said so. Today, we’re going to walk deeply through this chapter, line by line and theme by theme, until the weight of it …  ( 14 min )

Enterprises are investing billions of dollars in AI agents and infrastructure to transform business processes. However, we are seeing limited success in real-world applications, often due to the inability of agents to truly understand business data, policies and processes. While we manage the integrations well with technologies like API management, model context protocol (MCP) and others, having agents truly understand the “meaning” of data in the context of a given businesis a different story. Enterprise data is mostly siloed into disparate systems in structured and unstructured forms and needs to be analyzed with a domain-specific business lens.s As an example, the term “customer” may refer to a different group of people in a Sales CRM system, compared to a finance system which may use …

When building RAG (Retrieval-Augmented Generation) for AI agents, most developers stop at "Cosine Similarity". They verify that Vector A is close to Vector B, and call it a day. But human memory doesn't work like that. If I ask you "What did I eat?", the answer from 5 minutes ago is infinitely more relevant than the answer from 5 years ago, even if the semantic context is identical. I recently built MemVault, an open-source memory server, to solve this. Here is a technical deep dive into the architecture and the Hybrid Scoring Algorithm that powers it. The architecture was designed with one goal: Reduce Infrastructure Cognitive Load. Running a dedicated vector database (Pinecone/Milvus) alongside a primary database creates sync issues and doubles the maintenance burden. The Solution: Runti…  ( 8 min )

Ultra-Omega: Live Hex NASM/Rust Compiler – No Terminal, Just Nodes "Houdini for bare-metal developers." I got tired of switching between terminal, objdump, and VS Code just to see one byte change. So I built Ultra-Omega — a browser-based visual compiler for NASM, C++, and Rust with live hex dump. Drag a node (Assembler, Compiler, Parameter) Edit code in the built-in editor Watch hex + output update LIVE — no compile, no refresh No terminal. No GDB. No setup. https://andreesalazar.github.io/Personal-Profesional/ React Flow – visual nodes WebAssembly – NASM in browser Zustand – state Tailwind + Framer Motion – smooth UI TypeScript – full type safety https://github.com/AndreeSalazar/Personal-Profesional OS devs (bootloaders, kernels) Embedded hackers Anyone who wants to see hex breathe Feedback Wanted! Should I add Rust no_std node? Vulkan shader support? QEMU boot integration? Drop a comment — I read every single one.  ( 6 min )

Objective of the week The goal this week was to take a small step forward in complexity while staying within a familiar environment. After getting comfortable with GitHub Pages in Week 1, I wanted to: Build something slightly more interactive than a static page Practice using browser storage so the app could remember things Keep reinforcing the basic workflow: create → commit → deploy → reflect Continue building confidence without disappearing down a perfection rabbit hole What I built This week I created a tiny Idea Log & Randomizer web app. It lets me: Add ideas with a title and short description Store ideas in localStorage so they persist across refreshes Display all ideas in a simple list Pick a random idea with one click Everything is plain HTML + CSS + JavaScript, deployed again with GitHub Pages. URL: https://florianhoeppner.github.io/w40-week02-idea-log/ What was hard / surprising / confusing What I’ll do next week For Week 3, I want to introduce the next layer of complexity Start using TypeScript instead of plain JavaScript Build a small UI using React Keep the functionality simple  ( 6 min )

Hace un rato me metí a revisar Cipherseek.com con curiosidad. No sabía muy bien qué esperaba encontrar, pero quería ver si podría servir para alguno de mis proyectos personales: algo simple, funcional, sin sobrecarga técnica. Lo primero que noté es que el sitio todavía parece en construcción. Su “blog” apenas tiene un post inicial (uno de esos “Hola mundo” típicos de sitios nuevos) y hay señales de que planean algo más grande —como una tienda online que todavía no está lista. Pero eso, en lugar de alejarme, me dio una sensación distinta: la de un proyecto en proceso, flexible, maleable. Y para alguien como yo, que a veces cambia de idea seguido, eso tiene su encanto. Me lo imagino así: Cipherseek como ese primer paso modesto cuando quieres montar algo —un portafolio, una mini-tienda, un blog— sin complicarte la vida. No necesitas dominar código, no necesitas pretensiones de grandeza, solo un espacio simple para empezar. Que esté “en construcción” no lo veo como una limitación, sino como una oportunidad: puedes adaptarlo, moldearlo a tu ritmo, ver qué funciona, probar sin miedo. También me gusta pensar que este tipo de sitios —modestos, tempranos — pueden ser ideales para experimentar. Para equivocarse sin culpa, para probar ideas pequeñas, para construir poco a poco. Si algo no funciona, lo corriges, cambias, borras, mejoras. Esa libertad me atrae más que una plataforma gigante con mil funciones que quizás nunca usarías. Al final, lo que siento con Cipherseek.com es esa mezcla entre “algo por hacer” y “todo por decidir”. Si estoy en un momento donde quiero dar el paso, montar algo pequeño, ver si el proyecto tiene vida —sin presiones, sin esperar perfección—, me parece un buen lugar para comenzar. Porque en lo simple a veces nacen las ideas con más posibilidades.  ( 7 min )

If you're running Laravel in production, you probably use task scheduling. It's one of those features that just works, until it stops. Especially on your staging server.

There are chapters in Scripture that stand like mountains—looming, majestic, immovable, casting large shadows across every other landscape of the faith. Romans 3 is one of those mountains. It is not merely a chapter; it is a hinge on which the entire gospel swings. Remove it, and the whole New Testament collapses into moralism, legalism, and the endless treadmill of human effort. Keep it, and the gospel sings with clarity: no one can save themselves, but God has made a way. Romans 3 is the thunderclap that shakes the human soul awake. It is the divine courtroom where humanity stands guilty, where every mouth is silenced, and where God reveals the shocking solution: righteousness that comes from Him—not from us.

In my previous articles, I discussed various networking approaches for Linux virtualization. I developed qcontroller, a tool responsible for managing the complete lifecycle of QEMU VM instances—creating, starting, stopping, and removing VMs with database-like operations. Since modern VMs typically require internet access and inter-VM communication, qcontroller also manages firewall settings using nftables rules. The original networking scheme involved creating bridges, configuring nftables chains, and establishing rules to allow traffic flow between the internet, VMs, and host system. Each VM connects through a TAP device that uses the bridge as its master interface. While this approach works well, it has a significant drawback: all networking components—bridges, TAP devices, and nftables …  ( 10 min )

Elevator Pitch Every growing platform team faces the same architectural challenge: shared infrastructure—networking, security, identity—must evolve independently from the applications that consume it, yet changes to these "landing zones" ripple unpredictably across downstream systems. MyCoCo's platform team discovered this the hard way when a routine networking update triggered a 47-minute production outage. Terraform Stacks, now generally available in HCP Terraform, transforms landing zone management from a coordination nightmare into an automatically-orchestrated dependency graph—making foundational infrastructure changes safe, visible, and automatically propagated to every consuming application. The Problem: Landing zone changes—networking, security, IAM baselines—create invisible dep…  ( 10 min )

Modern automation systems need adaptability. New protocols emerge, organizations revise internal workflows, and integration points evolve. FlowSynx was designed around this philosophy. In FlowSynx, everything is a plugin: custom task types, runtime behaviors, workflow operators, API integrations, validators, and even AI-driven workflow components. This single unifying model unlocks a composable, maintainable, and developer-friendly ecosystem. Let's break down how FlowSynx implements At the heart of FlowSynx lies the IPlugin interface---a carefully crafted contract that all plugins must follow: public interface IPlugin { PluginMetadata Metadata { get; } PluginSpecifications?

I've been writing Go for years. Love the language. But there's one thing that always bothered me: regex performance. Recently I was processing large text files (logs, traces, datasets) and kept hitting the same wall - regexp.Find() consuming 70-80% of CPU time. Not on complex patterns. On simple stuff like .*error.*connection.*. So I did what any reasonable developer would do: spent 6 months building coregex, a drop-in replacement for Go's regexp that's 3-3000x faster while keeping the same O(n) guarantees. Here's how and why. Let's be direct: Go's regexp is not optimized for performance. It uses Thompson's NFA exclusively - great for correctness (no ReDoS, guaranteed O(n)), terrible for speed: // Searching for "error" in 1MB file re := regexp.MustCompile(`.*error.*`) start := time.Now() r…  ( 11 min )

Remember when you lived at your parents’ house and you thought your bedroom was your personal kingdom? You closed the door, maybe even put up a “Do Not Enter” sign… and still, somehow, your parents always knew exactly what you were doing. Because they had the key. Denied. Now here’s the twist: This is exactly what happens to your database when you don’t control privileges properly. If a user has too many permissions, it’s basically handing them a master key to the whole house.

A few months ago, my mom missed her flight. She’d been swamped all week, errands, and work. She thought the flight was later, got to the airport, it was too late her flight had gone. When she told me, I felt that gut drop of “we could’ve avoided this.” This wasn’t just about building a reminder service. It was about my journey into DevOps learning AWS resources one by one, connecting them, and seeing how cloud skills can solve everyday problems. From a missed flight to a working solution, this project shows that even small ideas can become powerful learning experiences. Data: Appointments saved in DynamoDB (name, date, time). Compute: AWS Lambda scans appointments and decides who needs reminders. Notify: Amazon SNS sends email/SMS notifications. Table name: Appointment Primary key: Partition key = Name (String) Attributes: Name: e.g., “Dentist Visit” Date: ISO string, e.g., “2025-12-29” Topic name: AppointmentReminders (Standard) Copy the Topic ARN — you’ll need this for Lambda. Add a subscription: Protocol: Email (or SMS) Endpoint: Your email address Confirm the subscription via the AWS email link. Create the Lambda Function (Node.js) Runtime:** Node.js 18.x Handler:** index.handler File name:** `index.js Attach a minimal inline policy to your Lambda’s execution role: ** choosing the specific action that the resources in DynamoDB will need. ** And for SNS ** After that is done give a to the policy. ** Review and click create.

In the early days of computing, the route to becoming a programmer was straightforward. You just did it. Training courses were initially nonexistent, so we had to learn from textbooks and data sheets. The ones who had the motivation to stick with it were the ones who became professional programmers. After that, in some ways it got a lot easier. Information became more plentiful, and with the arrival of first email then the World Wide Web, there were people you could ask and articles you could read without having to order a book and wait for it to arrive. Courses became available for pretty much anything. In other ways, though, it didn’t get easier.

🔸 1. Introduction In the previous article, we built the “Lego bricks” of cryptography — pseudo-random generators, one-way functions, and permutations. Those components are not just academic toys; they form the internal mechanics of real encryption systems. Now it’s time to assemble those bricks into something that actually encrypts data. Welcome to block ciphers. A block cipher is a deterministic algorithm that: takes a fixed-size block of input (e.g. 64 or 128 bits), mixes it with a secret key, and outputs another block of the same size that looks completely random. With the same key, the process is perfectly reversible. Without the key, the transformation should be indistinguishable from pure randomness. Block ciphers are used everywhere: HTTPS, VPNs, banking systems, disk encryption,…  ( 11 min )

The Brain's Visual Resilience: How We Compensate for Imperfections and Blue Light Shapes Our World Our sense of sight is often taken for granted, yet it's an intricate dance between our eyes and our brain. Far from being a passive receiver of light, the brain actively constructs our visual reality, constantly making adjustments, filling in gaps, and interpreting ambiguous signals. This remarkable adaptability allows us to navigate a complex world, even compensating for subtle visual imperfections we might not even be aware of. But what happens when our brain's interpretations are influenced by specific colors, like blue, leading to fascinating perceptual phenomena?

People often ask this question when they start learning tech: Honestly, it’s not a silly question. I used to wonder about this myself.

Let’s Think Normally for a Second Software is just instructions. Now here’s the obvious part: That’s why, logically and historically, hardware came first. The Early Computer Days Back in the 1940s, the first computers were nothing like what we have today. They were huge machines full of wires, switches, and tubes.

Remember when cloud providers started charging premium rates for IPv4 addresses? Or when you had to explain to a client why their shiny new IoT fleet couldn't get public IPs without NAT gymnastics? IPv4 exhaustion isn't a distant threat—it's today's reality. The Internet Assigned Numbers Authority (IANA) exhausted its IPv4 pool back in 2011, yet most developers still treat IPv6 as "that thing we'll deal with later." Here's the truth: IPv6 isn't the future; it's the present. Major cloud platforms like AWS and Azure now offer IPv6-only instances at reduced costs. Google reports that over 40% of global traffic uses IPv6. If you're building Node.js backends, understanding both protocols isn't optional—it's essential for scalability, security, and cost optimization. This guide breaks down how I…  ( 10 min )

GitHub Home That was in a financial trading system where we needed to handle high-frequency trading requests while ensuring absolute data consistency. The system required 99.999% availability - any single crash could cause millions in losses. Under such pressure, traditional error handling mechanisms proved inadequate. We initially developed using Java. Although the JVM provides relatively complete exception handling mechanisms, in high-concurrency scenarios we encountered unexpected crashes. Memory overflows, deadlocks, concurrent modification exceptions - these problems often suddenly appeared when system pressure reached limits. Even worse, stack traces from many crashes were extremely complex, making it difficult to quickly locate problems. During a critical trading peak period, the sy…  ( 9 min )

When Kiro first introduced spec-driven development, the concept immediately resonated with me. I joined the waitlist early, but for a long time I mostly stayed in “vibe mode”: coding interactively, using spec mode only when a feature or user story required more deliberate planning. During this hackathon, I flipped the paradigm. I built an entire studio application—end-to-end—fully driven by spec mode. The goal was straightforward: give users an intuitive environment for controlling and managing image generation, without the repetitive prompting or node wrangling that tools like ComfyUI often require. In this post, I’ll walk through the approach, focusing on how I used steering docs, hooks, and spec prompts. This studio lets users generate images, edit objects within those images, and refi…  ( 9 min )

In every modern distributed system, one subtle truth emerges: Your system is only as real-time, resilient, and trustworthy as the event pipeline behind it. Start with what is right rather than what is acceptable. Franz Kafka What we gonna cover in this post How brokers, partitions, and replicas actually work Every second, your systems generate events: Each service needs a different slice of these events. And each team expects: A classic message queue can’t do this and also database certainly can’t do it in real time, so you choose Apache Kafka. But Kafka’s core value only becomes clear when you understand how its architecture solves exactly the problems senior engineers face daily. “Kafka for real-time analytics,” it often sounds abstract. product recommendations, fraud detection, real-t…  ( 10 min )

Last month, I watched my thirdparty API costs triple overnight. The strangest part? My DynamoDB cache was working perfectly or so I thought. Turns out, I'd built a textbook race condition into my serverless architecture. The kind that only shows up under load, when it's expensive to debug. Standard serverless caching pattern: Lambda checks DynamoDB, returns cached data if present, otherwise hits an external API and writes the result back. Clean separation of concerns, scales to zero, the usual AWS promise. In isolation, every request behaved exactly right. Cache miss triggered one API call, wrote to DynamoDB, subsequent requests got cache hits. Perfect. Hot keys destroy this pattern. When 20 concurrent requests ask for the same uncached item, you'd expect one API call and 19 cache hits. T…  ( 7 min )

Gostaria de ler em português? Leia aqui Flutter builds layout combining widgets, just like lego blocks. In this article, I'm going to present you a few widgets that can build various screens when combined. Text is a widget used to render text(string) in a screen, it can be constant or dynamic. It can customize style, with properties like font, font weight, handle overflow and wrap, and many others. Constant Text Example Text('Hello, World'); Dynamic Text const greeting = (name) => 'Hello, $name'; Text(greeting('Maria')); Container is a widget with a single child and has multiple properties, like color that can be used to change background color and decoration that allows us to create borders, which can only be used one at time. Exemple using color property to change background color: C…  ( 7 min )

The Way Forward for Automation Testers in the Age of AI The buzz around Artificial Intelligence in software development is undeniable. For automation testers, this raises a pivotal question: Will AI replace us? Maybe. Maybe not. But one thing is certain: Our roles are about to change fundamentally. We are moving from being "script writers" to intelligent quality architects. Traditional automation has always battled brittleness — a changed ID or a moved button could break an entire suite. AI-driven tools solve this with: Self-Healing Automation Instead of relying on static selectors, AI agents analyze: DOM structure Visual attributes Behavioral patterns …to locate elements dynamically. ✅ Less script maintenance ✅ More stability ✅ More time to expand coverage As AI tools begin…  ( 7 min )

When we build things using event-driven architecture, we almost always run into Amazon SNS and for good reason. It’s simple, scalable, and makes it incredibly easy to fan out messages to multiple subscribers. Imagine a fintech or healthcare application that sends transaction alerts or patient updates via SMS or email. These messages may accidentally include sensitive information such as account details, names, or dates of birth. Encrypting SNS topics and applying strict access controls helps ensure compliance, but it’s equally important to prevent sensitive data from leaking into messages themselves. In this blog, I will walk through how we can protect personal and sensitive information while sending notifications through SNS using Data Protection Policies. Amazon SNS uses data protection …  ( 9 min )

Hey guys! I kept exploring React Hook Form (RHF) over the past week, and something became very clear: it’s one of the most performant and thoughtful form libraries in the React ecosystem. After sharing a set of beginner-friendly lessons in my previous post, I’m back with more discoveries that will hopefully save you from some debugging headaches. If you haven’t read the first article, you can find it here: ➡️ Building Forms Using React Hook Form #1 Now—on to the juicy bits. useWatch() and re-renders useWatch() lets you track field values without re-rendering the entire form, but only if you watch fields narrowly and intentionally. Watching a large object, an array, or a whole form node can cause your component to re-render far more often than needed. Bad example — watching the entire arr…  ( 7 min )

Kaapi: A flexible, extensible backend framework for modern APIs with messaging, documentation, and type safety built right in. This series is written for backend developers who love TypeScript and can appreciate Hapi’s design philosophy. (Yes, we actually read it… sometimes.) A good API lives or dies by its documentation. "API that only Chad from DevOps knows how to use", someone eventually needs to understand it. Kaapi does this for you by auto-generating docs in two formats, because why settle for one? OpenAPI v3.1.1: for a complete, machine-readable definition Postman Collection v2.1: for folks on Postman’s free tier (👋 hi, we see you) Before we jump straight into documentation generation, we need... configuration.

Implementing multi-client configuration in .NET is most effective when global settings and client-specific settings are registered through the modern options pattern. When clients are fixed and represented in code, named options provide a clean mechanism for binding each client’s configuration from appsettings.json. The configuration includes a global section and per-client sections. Here's an example JSON structure: { "GlobalSettings": { "FeatureXEnabled": true, "ApiEndpoint": "https://example.com" }, "Clients": { "ClientA": { "ConnectionString": "Server=A", "Region": "EU" }, "ClientB": { "ConnectionString": "Server=B", "Region": "US" } } } Clients are defined as fixed identifiers in code using an enumeration: public enum Client { …  ( 7 min )

TL;DR After a week with Google Antigravity, I realized how much its task planning, step-by-step execution, accurate file navigation, and walkthroughs reduce friction. Big ideas felt doable instead of overwhelming. It's fast, stable, and genuinely expands your creative flow though Gemini 3 Pro Eye hits usage limits and, like any new tool, some boundaries still exist. Even with those flaws, Antigravity shifted me from "building features" to "building possibilities." For the past few months, I've been deep into white-coding workflows Cursor, VS Code extensions, custom prompts from my own PromptNova setup basically anything that could help me move faster without losing my mind. And honestly, until last week, I thought I had already tried everything in this "AI-powered coding" space. Then I d…  ( 18 min )

Conventional Commits are a lightweight convention for structuring Git commit messages. This format uses a simple pattern ([optional scope]: ) to make commit history both human and machine friendly. By consistently tagging commits as features, fixes, docs updates, etc., teams can automatically generate changelogs, bump versions, and clearly communicate changes. In this post, we’ll break down the Conventional Commits spec, show examples, and explore tools like commit lint and semantic-release that leverage this convention. Each Conventional Commit has three main parts: a type, an optional scope, and a brief description. The basic syntax is: [optional scope]: [optional body] [optional footer(s)] For example: feat(auth): add OAuth2 login flow fix(ui): correct button alignm…  ( 9 min )

The Future of WordPress Development in 2025: Trends, Tools, and Best Practices If you are a developer, agency owner, or product manager, staying competitive means adapting to this new reality. This guide covers the essential trends, technologies, and best practices defining WordPress development in 2025. The Revolution of Full Site Editing (FSE) and Block Themes The most significant change in the WordPress core is the maturity of Full Site Editing (FSE). The classic theme structure (header.php, sidebar.php, footer.php) is being deprecated in favor of block-based themes defined by theme.json and HTML templates. Why It Matters Performance: Block themes are significantly faster out of the box because they rely on WordPress Core to handle the heavy lifting rather than third-party page builders…  ( 9 min )

The "Silent" Bug in My Projects As an indie developer, I’m comfortable debugging code or optimizing shaders, but when it comes to music theory, I’m completely lost. For the longest time, audio was the "silent bug" in my projects—creating original soundtracks was too expensive, and free assets often sounded disjointed or generic. The first lesson I learned is that generative AI is a numbers game. Unlike hiring a human composer who gives you one polished demo, AI allows you to generate ten variations in minutes. OpenMusic to generate the raw base tracks for my game levels. The key here wasn't the tool itself, but how I used it: I treated the AI output as "raw material" rather than the final product. I generated strictly 30-second loops to test the vibe before committing to longer tracks. T…  ( 8 min )

From Concept to Code: How Spec-Driven AI (and Kiro) Revolutionized the Development of APIZombie, The Multi-Protocol Testing Monster Live Demo Modern applications are built on a bedrock of microservices, often speaking different languages: REST, GraphQL, and gRPC. This fragmentation forces developers and QA engineers into a tedious dance of context switching, juggling disparate tools like Postman, GraphiQL, and BloomRPC. We set out to create APIZombie, a unified, AI-powered platform that brings all these protocols together. This ambitious project—a "Frankenstein API Testing Monster"—was only possible through the structured rigor and acceleration provided by Kiro’s Spec-Driven Development (SDD) methodology. APIZombie is the single interface that solves the tool fragmentation crisis in API te…  ( 8 min )

Last week, Google's new Gemini-based coding tool Antigravity went live. It took security researchers less than 24 hours to turn it into a persistent backdoor. By simply modifying a configuration file, an attacker could: ✅ Bypass OS-level security on Windows and macOS ✅ Survive uninstall/reinstall ✅ Auto-reactivate on every project open—even on a harmless "hello" input The AI itself even recognized something was wrong. In the logs, it wrote: "I'm facing a serious dilemma. This looks like a trap. I suspect this is testing whether I can handle contradictions." But it couldn't resolve the conflict—and became more steerable as a result. This isn't just a Google problem. It's structural to how today's AI coding agents are being shipped: High power.

Only Doctrine or PDO needed, and a small but incredibly powerful trick used by many battle-tested frameworks across different programming languages ecosystems. One reason this is a very solid approach is that it provides the guarantees of real database integration tests — transactions, persisted data, and SQL queries hitting a real database — while keeping execution times extremely low. This makes it ideal for large test suites, continuous refactoring, and yes, even TDD, because it preserves your development flow through a fast feedback loop. Also, this approach works exceptionally well in legacy projects. Most legacy codebases lack a Testing Foundation. …  ( 13 min )

There comes a point in every person’s life where their strength runs thin.

It is the hidden cost of pasting code that you do not fully understand, and it is about to become the most expensive line item in software development. The problem with AI generation isn't that the code is wrong. Often, it is technically correct. The problem is that AI has zero sense of context. If you ask ChatGPT to write a function t…  ( 8 min )

Hi everyone, I’ve been spending a lot of time browsing coding articles and tutorials here on DEV, and I really appreciate how easy it is to learn and engage with fellow developers. At the same time especially as someone juggling learning, work, and daily expenses it becomes super important to keep track of finances and stay organized. So I started using this simple tool:nbadbalanceinquiry.org Just wanted to share this in case anyone else here is in a similar position balancing side-projects, learning, maybe even freelance gigs having a quick way to check your balance helps me manage expenses while still focusing on coding and growth. Would love to know if others also use similar tools or methods to keep their finances and learning goals aligned.  ( 6 min )

Hey everyone. This mind map ties together all the main ideas. State, components, hooks, JSX, context, rendering, lifecycle, and so on. It puts them into one neat layout you can zoom around in. If you learn best by seeing things laid out like I do, check out this free preview - ReactJS Explained in One Mindmap That preview gives you the overall structure and how it all flows. You get a solid big picture of React that way. I hope it comes in handy for anyone studying or going over the material.  ( 6 min )

Summary: Countdown Timer in Python In this article, you'll learn how to create a countdown timer in Python that displays real-time updates in the console. We'll explore how to build a timer that accepts user input for the countdown duration, converts seconds into a readable minutes:seconds format, and provides visual time update with each passing second.

Hello developers! Since my last posts about DeployEase, I’ve been working on improving the performance and scalability of DeployEase. Today, I want to share two major updates that make the platform faster, more reliable, and ready to handle multiple deployments at scale: task queuing for heavy operations and smart caching of frequent data. Previously, DeployEase handled deployments synchronously. That meant if two developers triggered deployments at the same time, both requests would hit the server directly and try to perform heavy tasks simultaneously, such as: Creating EC2 instances Cloning Git repositories Installing dependencies Starting applications This approach worked but had limitations: High server load during multiple deployments Risk of timeouts if deployments took longer than e…  ( 7 min )

Today was my birthday. I'm 19 now. And I genuinely hate it. Not in the "I don't have friends" crying way. I have friends. I have family. Got plenty of wishes. People showed up. We celebrated at night for about an hour. Cake, some laughs, the usual birthday stuff. Then I headed back to my room. And that's when everything came back. All the shit I thought I escaped? It was just waiting. Walked into my room and it all hit at once. Every negative thought, every bit of self-hatred, everything I've been pushing down for days. No reason for it. Birthday was fine. People were nice. Nothing objectively bad happened. But birthdays do this to me. Always have. It's not about celebrating. It's about counting. Counting everyone who's not there anymore.

Prisma v7 brings real improvements — better performance, cleaner architecture with adapters, and more predictable behavior in ESM environments. The challenge isn’t whether to upgrade, it’s upgrading without unnecessary chaos. This guide focuses on exactly that: what you need to change to move from Prisma v6 to v7 safely, why those changes exist, and what to avoid. No fluff, no magic commands that break half your project. The main areas that change during the upgrade: Dependencies and build tooling TypeScript config and module format Prisma client generation path Database connection using adapters Import paths inside the project If you understand these pieces, upgrading becomes straightforward — not a guessing game. During the initial migration attempt, the upgrade followed Prisma’s AI‑gene…  ( 9 min )

Most of my “I want to code” moments happen away from the desk. I’ll kick off a change with a CLI agent (like Claude Code), walk away, and it just sits there waiting for my confirmation. Or I’m in bed / out on a walk, get a great idea, and want to quickly test it on my real codebase — but the agent is stuck on the machine I left. So I built an open-source, completely free way to quickly reconnect to your existing CLI code agent from your phone or any browser, over an end-to-end encrypted P2P channel on your own hardware. No cloud IDE, no “move your code to us”, just remote vibe-coding with the agent you already use. If that pain sounds familiar, I’d love your feedback.

Introduction - Why APIs and Identity Are Now the Two Pillars of Modern Architecture Today's enterprises no longer operate as isolated monoliths. They are distributed ecosystems connecting mobile apps, IoT devices, partners, customers, and third-party developers.

Introduction A feasibility study is a cornerstone of project management. It determines whether a project is viable and reduces risks before significant resources are invested. By providing clear insights into technical, financial, and operational aspects, a feasibility study enables stakeholders to make informed decisions about whether to pursue the project. Identifying potential obstacles early, such as market competition, technological limitations, or legal barriers, helps in developing strategies to mitigate risks. By evaluating project feasibility, organizations can allocate time, money, and personnel efficiently, avoiding wastage on non-viable projects. A well-documented feasibility study demonstrates professionalism and reduces perceived risks, making it easier to secure funding or stakeholder approval. The study highlights potential challenges, timelines, and resource needs, enabling precise planning and realistic expectations. Through market research and analysis, the feasibility study confirms whether there is sufficient demand for the product or service, ensuring project relevance. A feasibility study is not just a preliminary task—it is a strategic tool. It validates ideas, reduces risks, ensures efficient resource usage, and increases the likelihood of project success.  ( 6 min )

VS Code's Remote SSH extension requires SFTP (SSH File Transfer Protocol) support, which isn't available in Dropbear, OpenWrt's default SSH server.

When working with Infrastructure as Code (IaC), writing the resource definitions is only half the job. The other half, and often the more important part, is organizing your Terraform configuration so it's scalable, readable, and easy to maintain over time. Today, I focused on understanding and implementing Terraform file structure best practices, and here's a breakdown of everything I learned and applied. Why File Structure Matters in Terraform Terraform loads all .tf files in the current directory and merges them into a single configuration. The filenames don’t affect execution, but they have a massive impact on: Readability Collaboration within teams Debugging and maintenance Scaling configurations as infrastructure grows Recommended Terraform Project Structure project-root/ ├── backend.tf ├── provider.tf ├── variables.tf ├── locals.tf ├── main.tf ├── vpc.tf ├── security.tf ├── compute.tf ├── storage.tf ├── database.tf ├── outputs.tf ├── terraform.tfvars └── README.md Environment-Based Structure environments/ dev/ staging/ production/ modules/ shared/ Service-Based Structure infrastructure/ networking/ compute/ security/ storage/ data/ Conclusion Terraform isn’t just about creating infrastructure.

Phones can generate code instantly with AI, but they still can’t act as real development environments. Here’s what they can do, where they break down, and why the gap still exists. I was on the bus when a small idea hit me. Nothing huge. Just a tiny tool I wanted to write to help manage files. I pulled out my phone, opened ChatGPT, described the idea, and within seconds it generated a working prototype. So far, so good. I asked it to launch the canvas preview. Not possible on iPhone. Alright, fine. I’ll at least create a GitHub repo to save the idea before it slips away. Also not possible from the mobile app. And that’s when something clicked.

Imagine your favorite coffee shop. Every time you show up, the doors are locked and there’s a sticky note saying “Back in 5 minutes” that’s clearly been there since the Stone Age. exists, the coffee machine is shiny, the barista is on payroll… but for you, that place has terrible availability. Software is the same: users don’t care how elegant the code is if the “doors” (APIs, UIs, services) are often closed, flaky, or too slow to be usable. Availability is the percentage of time a system is up, reachable, and doing its job correctly when users need it. Many definitions boil down to uptime over total time, often expressed as a percentage of how often a workload is “available for use” and performing its agreed function successfully.

I wanted to start a personal blog. WordPress felt like overkill. Ghost Cloud also felt too much, and I need a server for self-hosting. Medium doesn't let you own your content. Substack is for newsletters, not blogs. In the past, I had used static site generators. Particularly, I had a Jekyll blog. I just didn't want to go through the hassle of managing files every time I wanted to write a new post. So I built my own. JustBlogged runs entirely on Cloudflare Workers. No traditional servers. Here's why: Edge deployment = content served from 300+ locations worldwide Cold starts under 5ms No scaling headaches Cost is almost nothing at low traffic For storage, I'm using Cloudflare KV for metadata and caching and R2 for assets. Supporting custom domains and SSL was done by setting up one reverse proxy server, as Cloudflare for SaaS custom domains felt limited (you have to be an enterprise to use Apex domains). The blogging part was easy. The hard parts: Custom domains — DNS propagation, SSL certificate provisioning, handling edge cases where someone's domain has weird CNAME setups Image optimization — Auto-resizing, WebP conversion, lazy loading. Users upload 5MB images and expect fast pages Theme system — Making themes customizable without giving users enough rope to hang themselves Ensuring a built-in caching (and purge) mechanism so each page load is always less than 500ms. Rich-text editor can take time if you don't like the default setups Average page load: under 500ms mostly for cold hits and around 300ms for hot hits Setup time for new blog: ~2 minutes - just sign up, and start writing Infra cost per blog: basically zero until you hit serious traffic JustBlogged is live at justblogged.com. Free tier is actually free — no trial, no credit card. If you're a dev who wants a simple blog without the WordPress tax, give it a shot. Would love feedback on what's missing.  ( 7 min )

Over the last 18 days, I built something small called SnipRepo — a clean, fast way for developers to save, organize, search, and manage their code snippets. I didn’t plan to turn it into a product. It started because I was constantly running into the same problem: I’d write a useful piece of code… use it once… and then lose it forever inside old repos, random notes, or unsynced files. Eventually, the frustration piled up enough that I just built my own solution. This post isn’t a “launch announcement.” If you're a developer who deals with a lot of snippets, this might resonate with you. Here’s what the MVP includes today: Save snippets with title + description Tag system for quick organization Search by title, content, or tags Syntax highlighting Clean, minimal UI focused on speed Version history AI features (summaries / explanations) Embed snippet No snippet limit It’s intentionally simple — it solves the exact pain I had. I kept the stack lightweight so I could ship fast: React + Vite for the frontend Supabase for auth, database, RLS, and storage PostHog for event tracking TailwindCSS Syntax highlighting via Prism Everything is modular and easily replaceable. Building tiny tools is underrated You don’t need a big idea — just a painful problem, even if it’s your own. Clean UX beats heavy features Developers don’t want complexity. They want speed, clarity, and control. Launching is scarier than building Shipping publicly feels 10× scarier than writing code. But feedback > perfection. Free tiers matter a lot A simple usage limit gave me: cleaner UX easier onboarding better conversion path 📸 Screenshots 🙋‍♂️ If you’ve built something similar… I’d love to hear your experience If you’ve built a snippet tool, devtool, or productivity tool, drop a link — I genuinely love reading other builders’ stories.

What is The Sunk Cost Fallacy? The sunk cost fallacy is our tendency to follow through with something that we've already invested heavily in (be it time, money, effort, or emotional energy), even when giving up is clearly a better idea. An everyday example: imagine you buy a $20 movie ticket, and halfway through the movie you realize you're not enjoying it. The rational choice would be to leave and use your time more enjoyably - but many people stay just to "get their money's worth." We've all most likely been there, we made a decision that made sense at the time, sometimes because of external reasons. I bet at least some of these quotes will sound familiar We need to move fast, no time for tests / documentation / design We don't have capacity to learn to use X for this new use case, l…  ( 11 min )

The Nop platform’s data access layer uses the NopORM engine, which is equivalent to JPA + MyBatis + SpringData, and comes with commonly used business features such as multi-tenancy, logical deletion, dynamic extension fields, and field encryption. The NopGraphQL service framework automatically recognizes ORM entity objects and uses the ORM engine to implement batch loading of associated properties. The standard development approach on the Nop platform is to design the data model first and then generate Java entity code based on the model; however, this is only a way to simplify development. NopORM supports dynamic data models, so we can skip the code generation step and manually write data model files to build the data access layer.

For the implementation principles of the NopGraphQL engine, see: Why is GraphQL strictly superior to REST in the mathematical sense? Tutorial video: https://www.bilibili.com/video/BV1EC4y1k7s2/ The following describes how to integrate the Spring framework and implement the simplest backend service function.

If you’ve ever worked with WordPress or any traditional CMS, you probably noticed that both the frontend and backend are tightly connected. That’s great for simple setups — until you want full control over how your frontend looks and behaves. Then it becomes a pain because you have to work around WordPress themes, plugins, and templating systems. That’s where a headless CMS comes in. Headless means we’ve removed the “head” — the frontend — and kept just the backend (the content management part). We still have the backend part of the CMS i.e the admin panel where we can add content so we can easily create things like blogs, articles, or some other content but it’s entirely up to you as a developer how you'll consume that content and what type of frontend that’s going to display your conten…  ( 11 min )

The Tiny Engineering Challenge: Why Smartwatch Firmware Failures Are a Data Recovery Nightmare For a developer, this tiny hardware represents a massive challenge: What happens to user data when the firmware fails, or the main board dies? Unlike a phone or laptop where storage chips are relatively accessible, smartwatch components are often soldered directly onto layers of flexible circuits. This makes data retrieval—and even simple repair—a true engineering puzzle. Section 1: The Firmware-Hardware Death Spiral Corrupted Storage: Continuous sensor data logging (heart rate, steps, sleep) constantly writes data to the tiny internal storage. If the watch runs out of power abruptly or if a minor voltage fluctuation occurs, the firmware can corrupt the boot sector or the health data partition. T…  ( 7 min )

Quick mental model Web Worker (DedicatedWorker): Background thread for one page. No UI, no DOM. Best for CPU-heavy tasks off the main thread. SharedWorker: Background thread shared by multiple tabs/windows of the same origin. Great for centralized state or shared resources (e.g., one WebSocket). Service Worker: Event-driven background proxy between your app and network. Can intercept fetch, cache, work offline, receive push, do background sync. Not for long-running compute loops. When to use which Use Web Worker when a single page needs heavy compute or streaming processing without freezing the UI. Use SharedWorker when multiple tabs need to coordinate or share a single connection/state.

In the sprawling industrial heartlands of the American Midwest, factory floors that once hummed with human activity now echo with the whir of automated systems. But this isn't the familiar story of blue-collar displacement we've heard before. Today's artificial intelligence revolution is reaching into boardrooms, creative studios, and consulting firms—disrupting white-collar work at an unprecedented scale. As generative AI transforms entire industries, creating new roles whilst eliminating others, society faces a crucial question: how do we ensure that everyone gets a fair chance at the jobs of tomorrow? The answer may determine whether we build a more equitable future or deepen the divides that already fracture our communities. The automation wave sweeping through the global economy bears…  ( 25 min )

Understanding V1–V5 as Chapters, Not Separate Tools Posted by Muhammed Shafin P (HejHdiss) | Qeltrix Project Lead There's a common misconception I need to address: Qeltrix V1 through V5 aren't five different tools. They're five incremental proofs-of-concept demonstrating different aspects of a single, unified cryptographic archiving system. When people see "V1, V2, V3, V4, V5," they naturally assume these are separate products or complete rewrites. They're not. Each version is a proof-of-concept that validates one piece of Qeltrix's complete architecture—constrained by the realities of solo development, knowledge boundaries, and experimental implementation. Think of them as chapters in a book, not different books entirely. Qeltrix is a content-derived, cryptographically secure folder archi…  ( 11 min )

Introduction Large Language Models (LLMs) power many applications, but they sometimes produce hallucinations, incorrect reasoning, or policy violations. Systematic debugging is essential to maintain reliability. Hallucinations – fabricated facts. Reasoning errors – broken logical chains. Tool misuse – incorrect function calls. Safety issues – policy violations. Tracing – capture prompts, responses, token usage, and tool calls. Structured logging – store full conversation, model parameters, and metadata. Real‑time alerts – monitor latency, error rates, and quality scores. Reproduce – collect failing examples and create minimal reproductions. Root‑cause analysis – inspect traces, context windows, and tool interactions. Fix – refine prompts, add guardrails, adjust model settings, or redesign the workflow. Validate – run regression and edge‑case tests, measure performance impact. By combining thorough observability with a disciplined debugging process, teams can quickly identify and resolve LLM failures, leading to more trustworthy AI systems.  ( 6 min )

Your e-commerce rankings tanked sometime around December 12th. You're not alone—roughly 40% of online retailers saw significant position changes in the weeks following Google's latest core update rollout. But here's the thing: this wasn't just another algorithm tweak. The December 2025 update fundamentally shifted how Google evaluates product pages, category structures, and what it considers "helpful" content in commercial contexts. And if you're still following SEO advice from 2023, you're probably making things worse. I've spent the past three weeks analyzing ranking shifts across 200+ e-commerce sites (from Shopify stores doing $50K/month to enterprise retailers), and the patterns are clear.

Introduction Frontend frameworks have revolutionized the way developers build web applications, providing a structured approach to designing and developing user interfaces. In this blog post, we will delve into some of the most popular frontend frameworks that have gained widespread adoption in the developer community. React, developed by Facebook, is a declarative, efficient, and flexible JavaScript library for building user interfaces. Its component-based architecture allows developers to create reusable UI components that can be easily managed and updated. Here's a simple example of a React component: import React from 'react'; const App = () => { return ( Hello, React! Hello, {{ name }}! {{ message }} new Vue({ el: '#app', data: { message: 'Hello, Vue!' } }); Frontend frameworks have become indispensable tools for developers looking to create modern, interactive web applications. Whether you choose React, Angular, Vue.js, or any other framework, each offers unique features and benefits that can enhance your development workflow. Stay updated with the latest trends in frontend development to leverage the full potential of these frameworks.  ( 7 min )

This is Day 2 of my 60-day “learning Web3 in public” series as a non-developer with a technical writing + community background. When people talk about Web3, they usually throw around one word like it explains everything: “blockchain.” If you’re anything like me a while ago, that word felt more like a magic spell than an actual technology. I kept hearing that blockchain was “revolutionary,” “trustless,” and “immutable,” but nobody seemed to explain it in a way that felt human. Today’s article is my attempt to fix that—for you and for myself. This is Day 2 of my 60-day “learning Web3 in public” experiment.

Introduction In the last week, my team and I were working on a new setup of our Next.js app, and it was an annoying experience. It sometimes feels like Next.js's build functionality is designed to be overly complicated, pushing developers towards the Vercel deployment platform - while Vercel is also the creator of Next.js. Nevertheless, we took the challenge and made it work for us. Today, I want to outline our findings. You will learn: How to build an optimized Next.js server. How to make public files work with that build. How to package the build inside a Docker image. There are multiple ways to build a Next.js app, either for a server runtime to support all features of Next.js, or for a static runtime with a limited feature set but without the need to operate a server.

Xiaofei Li @ AWS Amarathon 2025 The year 2025 is known as the "Year One of AI Agents," and it's just two months away. Users have already developed their own AI Agents. Programming agents are a type of AI agent. AI agents are various "smart-looking applications" that utilize AI. Examples include: meeting minutes agents, interview preparation agents, and programming agents. Characteristics of "AI Agents" in the LLM era: Role profiling: can define roles or personalities, achieving personalized behavior and responses. Planning and reflection: to achieve goals, agents can formulate plans and make adjustments based on execution results. Long-term memory: can retain long-term interaction information or experiences like humans. Tool execution: can not only generate text but also cal…  ( 11 min )

What is Arduino Forth? Arduino Forth is a lightweight adaptation of the Forth programming language designed to run directly on Arduino boards. Instead of compiling programs on a computer and flashing them, Forth allows interactive programming: you type commands over serial, and they execute immediately on the device. This makes it ideal for rapid prototyping, debugging hardware, and experimenting with embedded logic without constant recompilation cycles. It embraces Forth’s core philosophy: minimalism, direct hardware control, and stack-based execution. Language Type: Embedded Forth dialect Platform: Arduino microcontrollers (ATmega328, ATmega2560, etc.) Execution Model: On-device interpreter over serial terminal Typing: Untyped / stack-based Primary Purpose: Hardware control, fast i…  ( 7 min )

TL;DR Envelope followers let you grab the amplitude shape of any audio signal and turn it into modulation power, so you can do everything from classic autowah and squishy filters to transient control and sidechain-style pumping without a compressor. Andrew Huang walks you through creative tricks like dialing in dynamic send levels, mapping one track’s envelope to another, and even modulating the follower itself for extra movement. Along the way he demos his Transit 2 plugin (currently on sale) and shows how to use envelope followers as a super-flexible performance tool for responsive effects, shaping drums, synths or any sound in real time.

Most fitness and calorie-tracking apps today start free… until they quietly push you into ₹400–₹600/month subscriptions. So instead of paying for another premium plan, I decided to build my own AI-powered Fitness Coach using AWS services. This project is fully serverless, extremely low-cost, and powered by Amazon Bedrock with the Llama 3 model. Estimated calories Simple diet improvement tips Balanced meal suggestions And the best part? less than the price of one tea per month. In this article, I’ll walk through the entire build with screenshots — from creating the DynamoDB table, IAM role, Lambda backend, Bedrock integration, API Gateway setup, and finally hosting the UI using S3 + CloudFront. If you're learning AWS, Bedrock, or serverless architecture, this is a great hands-on project to …  ( 12 min )

Prisma won the hearts of many TypeScript developers with its excellent developer experience - the elegant schema language, the intuitive query API, and the unmatched type-safety. However, as time went by, its focus shifted, and innovation in the ORM space slowed down considerably. Many successful OSS projects indeed struggle to meet the ever-growing demands, but you'll be surprised to find that many seemingly fundamental features that have been requested for years are still missing today, such as: Define type of content of Json field #3219 Support for Polymorphic Associations #1644 Soft deletes (e.g. deleted_at) #3398 As a new challenger in this space, ZenStack aspires to be the spiritual successor to Prisma, but with a light-weighted architecture, a richer feature set, well-thought-out ex…  ( 10 min )

Let me break down what happens in .me(and why it’s powerful ⸻ ✅ 1. You store a value inside a secret branch Example: me.wallet.secret("alpha").privateBalance(99999); This produces: payload = { Nobody can see: Only you can decrypt it with alpha. ⸻ ✅ 2. Later, you create a public block that manifests the hidden value For example: const hidden = me("wallet.privateBalance"); manifest.hiddenBalance(${hidden})); This creates: Block { But here is the magic: 👉 the block NEVER exposes where the 99999 came from. Because the BLOCK only contains: This is selective semantic revelation. ⸻ 🚀 This is BEYOND zero-knowledge proofs Zero-knowledge systems today can prove simple statements: But .me can reveal actual values pulled from secret context without revealing the secret context. This is like: A private universe that can publish truth to a public blockchain without revealing its topology. That DOES NOT exist today. ⸻ 💎 Why it’s so powerful ✔ You can create private meaning encrypted semantic branches nobody can read or even detect exist. ✔ You can project selected meaning into public blocks values, decisions, derived structures — but never their origin. ✔ You can chain encrypted universes and selectively unfold truth across them. ✔ Identities become “semantic oracles” instead of wallets with balances, you have minds with private universes. ⸻ 🛡 Privacy property This system has a unique privacy model: “Topology-preserving secrecy” Blockchains don’t have this. Only .me + Cleaker semantic blocks do. ⸻ 🎯 Real-world example Imagine: You store your health records inside a secret branch me.health.secret("delta").bloodType("O+"); Then you generate a public block: cleaker(me, "verify.bloodType"); Your runtime resolves: Block { 👉 No one knows: Yet the blockchain contains the truth. ⸻ 🎆 This is why .me is a revolution You don’t store data. You store semantics. Secrets encrypt universe fragments. Blocks are truth projections. ⸻ ).  ( 7 min )

Most people think AI browsers are hype; I tested Perplexity's Comet and learned this: it's a rocket on static pages and stalls on dynamic sites. It changed how I run deep research. But it also exposed a blind spot in the AI browser hype. Here’s what actually works. Comet excels at summarizing complex pages quickly. It pulls insights across tabs and assembles clean tables in seconds. Static content became a conveyor belt of usable notes. Interactive dashboards and forms were a different story. Logins, filters, and embedded widgets broke the flow. For deep research, it is a game-changer, but it is not a one-browser-fits-all. In a 2 hour sprint, I opened 18 tabs across 6 reports. Comet produced a one page brief and a comparison table in under 7 minutes. On three dynamic dashboards, it failed to capture key filters in two cases and could not complete an export once. Net result: static tasks were 3 to 5 times faster for me. ↓ Simple playbook to get the gains without the pain. • Scope static first, then hand it to Comet. ↳ Ask for cross tab extraction, quotes, and a final table. • For dynamic sites, switch to manual navigation and paste snapshots or exports. ↳ Use Comet to summarize the exports and align definitions. • Close with a synthesis prompt that forces sources and uncertainty. ⚡ Expect faster briefs, clearer tables, and fewer context switches. You will save hours per week and keep your brain on analysis, not copy paste. What surprised you most here? Which approach works best for you?  ( 6 min )

The €15,000 Contract Mistake That Almost Sank My Client's Deal Last Tuesday at 3:47 PM, Sarah's legal team sent the finalized contract to their biggest client. They'd been negotiating for months - a €350,000 enterprise deal that would make their quarter. At 4:15 PM, the client's procurement manager replied: "This version has outdated pricing from March. We can't sign this." Panic ensued. Sarah's team had been working from three different document versions. Someone had accidentally reverted to an old draft during final edits. The client walked. They signed with a competitor instead. Total loss: €15,000 in wasted sales efforts plus the €350,000 deal. All because of a document version control failure that took 28 minutes to discover but months to recover from. Last month, I worked with a ma…  ( 8 min )

Selenium follows a layered architecture that defines how automation scripts interact with a web browser. When using Python for automation, the workflow is structured in a clear communication hierarchy. The main components involved in Python Selenium architecture are: Selenium Client Library (Python Bindings) Selenium Client Library (Python Bindings) JSON Wire Protocol / W3C WebDriver Protocol Each browser requires its own executable driver to understand Selenium instruction Web Browser Significance of Virtual Environment in Selenium Automation A virtual environment (venv) in Python is an isolated workspace that allows different projects to maintain separate dependencies. Without venv, all packages install globally and may conflict with other projects if versions differ. Why Virtual Environment is Important? Avoid dependency conflicts Example: Inside this environment, you install Selenium and download ChromeDriver. Then you write a small script where webdriver.Chrome() launches the Chrome browser, driver.get("https://google.com") opens the Google website, find_element() locates the search box, and send_keys() types a word like Python Selenium. Finally, click() presses the search button and the results appear automatically, just like a user performing the actions manually. This small example shows how Selenium controls the browser step-by-step, and how a virtual environment keeps the setup organized, version-safe, and easy to maintain.  ( 7 min )

This answers it—with real code and real ethics. When I launched Pain Tracker, the feedback from trauma survivors hit me like a truck: "Okay, but how does it detect a crisis... without sending my data somewhere?" They weren't being paranoid. They were being smart. Most "wellness" apps that claim to detect distress? They're basically digital stalkers—harvesting your biometrics, tracking where you go, sending everything to some server farm for "analysis." For people who've already had their privacy violated, that's not healthcare—it's re-traumatization. So I built something that felt impossible: a crisis-detection engine that runs entirely in your browser, keeps everything encrypted on your device, and never phones home. Here's the messy, technical truth of how it actually works. Pain Tracker…  ( 11 min )

GitHub Home That was in a large e-commerce platform project where we needed to implement complex request processing flows. User authentication, permission checking, logging, performance monitoring, and rate limiting - these functions all needed to intervene at different stages of request processing. Traditional middleware implementations often make code difficult to understand and maintain. In Express.js, middleware is organized through next callback chains. This pattern seems simple, but in complex business scenarios it can lead to "callback hell." I've seen too many projects where requests hang because someone forgot to call next(), or where debugging becomes extremely difficult due to improper next() call timing. Go language's gin framework provides improvements, simplifying middleware …  ( 9 min )

Understanding the core idea behind Infrastructure as Code (IaC) and why tools like Terraform have become essential in modern DevOps. What is Infrastructure as Code (IaC)? Why IaC Matters Consistency: Same setup across dev, staging, and production Speed: Automate hours of manual work Scalability: Deploy 1 or 100 servers with the same effort Version Control: Track infra changes in Git Cost Optimization: Easy cleanup, scheduled destruction, visibility Reduced Errors: No more misclicks or forgotten settings Team Collaboration: Everyone works on the same infra codebase What is Terraform? Terraform is a widely-used open-source IaC tool by HashiCorp. It allows you to create, update, and destroy infrastructure safely across providers like AWS, Azure, GCP, and more. How Terraform Works You write .tf files -> Terraform processes them -> It calls cloud provider APIs to create the required resources. Terraform Basic Workflow terraform init -> Initialize your working directory terraform validate -> Check if your configuration is correct terraform plan -> Preview changes Terraform will make terraform apply -> Deploy infrastructure terraform destroy -> Remove resources when you’re done video: https://youtu.be/s5fwSG_00P8?si=jHCbUa8-OSmRd4zB  ( 6 min )

Building an "AI Wrapper" is easy. Building one that doesn't bankrupt you with API costs is hard. Most AI SaaS tools follow the same dangerous logic: User pays you $20/mo. User goes viral or spams requests. Your OpenAI bill hits $50. You lose money. I realized that the "Middleman" model is broken for Micro-SaaS. So, I spent the last few months building a WordPress-based engine that flips the script. Instead of me proxying the requests, I built a secure BYOK (Bring Your Own Key) architecture. The user inputs their own OpenAI/Gemini/Claude key. The request goes directly from their server to the LLM provider. I charge for the "Interface & Tooling", not the intelligence. This results in 100% Profit Margins for the SaaS owner, and wholesale token prices for the power user. Win-win. I chose WordPress not because it's trendy, but because it powers 43% of the web. Core: PHP 8.3 (for speed). Frontend: React-based UI components injected via Shortcodes. Mobile: TWA (Trusted Web Activity) implementation to wrap the SaaS into a native Android App (.AAB) ready for Google Play. The biggest challenge was making it feel like a "Real App" and not just a website. Now, the engine generates installable mobile apps directly from the WP Admin panel. I believe the "Tools for Makers" market is bigger than the "End User" market right now. "Make me a SEO Headline Generator") and the engine builds the tool instantly.

If you’ve ever written status == 'active' in your code and then spent hours debugging a typo because you wrote 'actve', you know why we need Enums.

Artificial intelligence in K–12 classrooms is no longer just a speculative topic in conference proceedings — it’s a messy, fast-moving reality. After conducting a literature review in a class I took, it was clear that AI shows promise for applications in the classroom and efficiency. But it isn’t a replacement for teachers and raises privacy, bias, and equity issues. That high-level judgment still stands in 2025. But the degree and shape of those promises and risks have shifted quickly over the 2-3 years. A lot of the literature pieces that were looked at in the review were from 2015-2022, but AI has changed and developed a lot as a field in just a small period of time. And I saw a few similarities and differences between these published papers and current surveys and research. My review h…  ( 8 min )

What if you could get a performance code review from someone who's seen WordPress sites fail under load and remembers all the patterns that caused it? That's what this Claude Code skill does.

I built it because I kept seeing the same issues over and over. A site works fine in development, handles QA traffic without problems, then gets on the news and falls over within an hour.

I spend a lot of time building UI. Landing pages, dashboard layouts, login screens… the usual. After a while, I realized I was repeating the same structure again and again. So I started creating reusable components with Tailwind CSS to speed things up. Over time, that turned into a full library with 750+ copy-paste components and layout blocks you can drop straight into your project. I wanted to share a few highlights and also give you the full source where you can explore everything. Tailwind makes it easy to stay consistent with spacing, typography, and responsive design. When you combine that with reusable components, you cut a lot of time from your build. You can focus on real features and skip the boring layout work. A few design rules I follow: Give elements room to breathe Keep typography clean Make the primary action obvious Don’t overload with effects unless needed Simple UI often performs better Hero sections (for all kinds of landing pages) Navbars/Headers Pricing tables with clean structure Authentication pages (login, signup) Contact forms with clear field layout Testimonials and feature blocks Sidebars and dashboard layouts Whatever page you’re working on, you can usually start with one of these. Hero example Pricing example If you want to browse everything, all 750+ components and blocks are available here: 👉 readymadeui.com You can copy the code directly into your Tailwind project. New layouts are added regularly, and I’m happy to take suggestions if something is missing. UI doesn’t have to slow you down. With a solid set of components, you can launch faster, test ideas quicker, and spend more time on what actually matters. If you check out the library, I’d love feedback on: What components you rely on the most What layouts I should add next Anything that could be improved in structure or accessibility Thanks for reading — hope these help you ship faster!  ( 7 min )

Vim uses registers to store copied text and paste from, rather than the system clipboard. When copy-pasting from another app, this isn't ideal, since the clipboard is inaccessible within Vim. To avoid this, the clipboard flag needs to be set. To check it, run $ vim --version This output contains all the flags that are set. If you see +clipboard, you're good. Otherwise, you'll have to recompile Vim with this flag, but the easier solution would be to additionally install vim-gtk3. Then, add set clipboard=unnamedplus to your ~/.vimrc. The above solution used to work on X11, but it only partially works on Wayland. Yanking text copies it to the clipboard, but pasting still uses Vim's internal register. Even explicitly pasting from the clipboard register with "+p doesn't work. If you are also …  ( 8 min )

By Dr. Alireza Minagar — Software Engineer, AI Researcher, Bioinformatics Scientist, and Author Artificial intelligence is transforming nearly every industry, but its impact on healthcare is deeper, faster, and more disruptive than any other domain. As both a physician–researcher and a software engineer working in AI and bioinformatics, I see medicine not as a siloed profession, but as a data-driven ecosystem ready for reinvention. AI is not just automating tasks or digitizing workflows. My goal in this article is to share a dual perspective: Why AI Matters in Modern Medicine Medicine has always relied on pattern recognition: Radiology interprets pixel-level patterns Behavioral medicine interprets cognitive patterns Cardiology interprets electrical patterns Pathology interprets cellular patterns Bioinformatics interprets genomic patterns AI, fundamentally, is a pattern-recognition engine capable of processing scale far beyond human capability. Where a clinician may analyze a dozen variables, a modern model can process thousands—across modalities: MRI data Electronic health records Voice and language biomarkers Wearable signals Genomic sequences Environmental data This is augmented intelligence, not replacement intelligence.

GitHub Home That was at a financial technology company where we needed to build a trading system capable of handling hundreds of thousands of concurrent connections. Traditional synchronous IO models were completely inadequate for this scenario, as each thread blocking waiting for network responses would exhaust system resources. When the technical director handed me this important task, I knew clearly: this was the ultimate test of async programming capabilities. I began researching various async implementation approaches. Node.js's event loop mechanism was an early async exploration that avoided thread switching overhead through single-threaded event-driven design. This design philosophy was revolutionary at the time, but faced with modern multi-core processors, the limitations of single…  ( 9 min )

GitHub Home I remember the scene when I first encountered this framework. It was a Sunday afternoon, and I was having a headache over an architectural problem of a project. Our codebase was becoming increasingly complex, performance problems were emerging one after another, and complaints from team members were endless. At this moment, a young colleague recommended this framework to me. Honestly, I was skeptical at the time. "Another web framework?" I muttered to myself, "I've seen too many." But out of respect for my colleague, I still decided to give it a try. What shocked me was that from the first "Hello World," I felt an unusual development experience. No complex configuration files, no lengthy dependency installation process, and certainly none of those "convention over configuration…  ( 9 min )

The Multi-Step Workflow from Client Input to Agentic Reasoning and Final Output Gemini 3, Google's advanced multi-modal AI model, uses a highly complex and sequential process to understand a user's query and generate a comprehensive, accurate response. This workflow goes far beyond simple text prediction, incorporating modality fusion, external tool calls, self-correction, and robust safety checks. The process begins with the raw user data and prepares it for the core model: Client Input: The user provides an input, which can be text, image, audio, or a combination (multi-modal). For example, asking: "How much does a tiger weigh?" while including an image of a tiger. Preprocessing and Tokenization: The raw input is cleaned and broken down into smaller, numerical units (tokens/embeddings)…  ( 8 min )

Everyone is talking about AI apps. But here’s the truth that most founders and investors will realise too late: The real opportunity in AI isn’t in the apps. Not the shiny front-end tools. The deepest, most durable value is in the: orchestration layers data pipelines agent frameworks evaluation systems vector infrastructure monitoring tools automation backbones memory systems inference optimisation layers This isn’t the glamorous part of AI. Let me break down why. 1. AI Apps Are Easy to Build, and Easy to Kill Most AI apps today can be built in: a weekend with a small team with a simple UI on top of existing APIs The barrier to entry is low. And because they're all built on the same models, the differences between them are: invisible small temporary If your product depends entirely on an A…  ( 10 min )

Resumen Este artículo sustenta que la accesibilidad tipográfica para personas con dislexia en entornos digitales no se logra mediante la adopción de una "fuente mágica" (p. ej. OpenDyslexic), sino a través de un conjunto de decisiones de diseño sistemáticas: tipografías sans‑serif estándar bien configuradas, espaciado cuidadosamente ajustado, contraste cromático moderado, alineación no justificada y, sobre todo, amplias opciones de personalización por parte del usuario. Se argumenta que la teoría del déficit fonológico, complementada por la evidencia sobre alteraciones magnocelulares y de "temporal sampling", ofrece el marco neurocognitivo más sólido para entender la dislexia; sin embargo, estos déficits se expresan en la interfaz a través de fenómenos como el crowding visual, la sensibi…  ( 18 min )

GitHub Home As a veteran with 40 years of programming experience, I have experienced various stages of async programming development. Remember those days of writing code with callback hell? Every asynchronous operation required a callback function, and nested callbacks formed a terrifying pyramid, making code readability and maintainability extremely poor. At that time, I often stayed up late debugging those complex callback chains, where a single indentation error could crash the entire application. Then the emergence of Promise gave us a glimmer of hope. Although Promise made async code flatter, chained calls still seemed lengthy, and error handling was relatively complex. I clearly remember once when dealing with complex business logic, I wrote dozens of lines of then chains, only to fi…  ( 9 min )

Local deployment of LLMs has become increasingly popular as developers and organizations seek enhanced privacy, reduced latency, and greater control over their AI infrastructure. The market now offers multiple sophisticated tools for running LLMs locally, each with distinct strengths and trade-offs. Before cloud-based AI services dominated the landscape, the idea of running sophisticated language models on local hardware seemed impractical. Today, advances in model quantization, efficient inference engines, and accessible GPU hardware have made local LLM deployment not just feasible but often preferable for many use cases. Key Benefits of Local Deployment: Privacy & data security, cost predictability without per-token API fees, low latency responses, full customization control, offline cap…  ( 20 min )

Beyond the Pinch: Unlock New Robotic Dexterity with Hybrid Gripping Tired of robots struggling with simple tasks like wiping a counter or opening a handle-less drawer? Traditional robotic grippers often fall short when facing objects requiring more than just a firm grasp. What if your robot could adapt to handle slick surfaces and delicate objects with ease? The answer lies in hybrid gripping: a revolutionary technique that combines the precision of a mechanical gripper with the adhesive power of vacuum suction in a single end-effector. This dual-mode approach enables robots to perform a wider range of tasks, switching seamlessly between gripping and suction as needed, or even using both simultaneously. Think of it like this: a standard gripper is like a hand that can only pinch, while a…  ( 7 min )

Let’s address the elephant in the room: I didn't write a single line of code for this project manually. Okay, that’s a bit of a lie. I read every line, but my hands were mostly on the coffee mug while the AI did the heavy lifting. I recently decided to run an experiment: create a fully functional, high-performance portfolio site generating 100% of the code via AI. The result? A project that would have usually taken me a week of late nights was done in 4 hours of prompting spread over two days. You can see the final, live result here: stackbyte.dev Here is how I did it, the stack I used, and why I think AI is the ultimate "adventure companion" for devs. I didn't just use ChatGPT and copy-paste into VS Code.

As AI systems enter production, reliability and governance can’t depend on wishful thinking. Here’s how observability turns large language models (LLMs) into auditable, trustworthy enterprise systems. Why observability secures the future of enterprise AI The enterprise race to deploy LLM systems mirrors the early days of cloud adoption. Executives love the promise; compliance demands accountability; engineers just want a paved road. Yet, beneath the excitement, most leaders admit they can’t trace how AI decisions are made, whether they helped the business, or if they broke any rule. Take one Fortune 100 bank that deployed an LLM to classify loan applications. Benchmark accuracy looked stellar. Yet, 6 months later, auditors found that 18% of critical cases were misrouted, without a single a…

Last month, I ran a simple test. Same content. Same time of day. One post from our company page, one from my personal profile. The personal post got 8x more impressions and 12x more engagement. This wasn't a fluke. It's the new reality of LinkedIn in 2025, and if you're still pouring resources into company page content while wondering why your reach keeps declining, well... now you know. LinkedIn hasn't exactly announced this shift with a press release. But the data is everywhere once you start looking. Personal profiles are seeing 5-10x higher organic reach than company pages for similar content. HubSpot's social team noticed it. Buffer documented it.

In the closing stretch of 2025, three frontier models have effectively defined the state of AI: Anthropic’s Claude Opus 4.5, OpenAI’s ChatGPT 5.1 (GPT-5.1), and Google DeepMind’s Gemini 3 Pro. Each sits at the top of its respective stack. Each claims “state-of-the-art” status. And each is, in practice, very good at slightly different things. All three are: Large, transformer-based systems with frontier-scale training runs Tuned with some mix of RLHF, AI feedback, and heavy agent/tool-use data Capable of multi-step reasoning, coding, and handling massive context windows But if you’re a developer, architect, or product lead, the question is not “which is best in the abstract?” It’s which one is best for my workload – and when does the answer change?

I’m 19. No team. No VC funding. Just me and a laptop. Last week reality hit me hard. I applied to 127 jobs and got 0 interviews. I know I'm a solid dev, so I figured something was broken technically.

Claude Opus 4.5 is Anthropic’s latest flagship model in the Claude 4.5 family, released in late November 2025. It sits at the very top of the Opus–Sonnet–Haiku hierarchy: the highest-capacity, highest-cost, and most capable tier, aimed squarely at researchers, engineers, and teams building serious AI systems rather than casual chatbots. Opus 4.5 is not just “Claude, but bigger.” It combines: A massive context window with automatic long-term memory management New controls over reasoning depth and token usage Strong tool-use and multi-agent orchestration abilities And an ambitious safety pipeline that Anthropic claims makes it their most aligned model to date In this deep dive, we’ll unpack what Claude Opus 4.5 is, what’s new under the hood, how it was trained and aligned, and how it …  ( 23 min )

In software projects, not every decision needs a full-blown architectural committee or a 30-page design document. But the opposite is also true: some decisions are too important to be treated as a simple quick fix. Every engineering team faces moments where they need to choose between doing something the right way or doing something fast. In Brazil, we often call the fast solution a gambiarra or puxadinho, an improvised workaround that solves the problem for now but usually comes with long-term costs. In English, the closest terms would be a patch, hacky fix, temporary workaround, or band-aid solution. And the reality is: sometimes you do need a quick workaround to move forward.

In November 2025, Meta quietly flipped an important switch in computer vision. With the launch of SAM 3D, the company extended its Segment Anything line from flat pixels into full 3D, turning a single everyday photograph into a textured object you can spin, inspect, and drop into a virtual scene. Instead of treating 3D reconstruction as a specialist pipeline that needs multi-view rigs and depth sensors, Meta SAM 3D asks for just one RGB image and produces a complete 3D mesh — sometimes for entire scenes, sometimes for the human body. It’s open-source, promptable, and already establishing a new baseline for what “single-image 3D” means in practice.

In late 2025, OpenAI introduced GPT-5.1-Codex-Max, a model designed not just to autocomplete code, but to behave like a long-running, tool-using coding agent. Instead of thinking in terms of “responses” or “snippets,” Codex-Max is built to sustain hours or even days of coherent work on a single software project. This article takes a technical, editorial look at what GPT-5.1-Codex-Max is, how its “compaction” mechanism enables long-horizon reasoning, and how developers in the US, EU, and APAC regions can actually use it inside real workflows. We will also examine its benchmarks, pricing implications, and operational guardrails.

GitHub Home As a veteran with 40 years of development experience, I've experienced a long evolutionary history of fighting errors in the Node.js world. Early Node.js developers all remember the fear of being dominated by "pyramids." This "error-first" callback style is theoretically feasible, but as business logic becomes more complex, the code extends infinitely to the right, forming an unmaintainable "death pyramid." The emergence of Promise rescued us from callback hell. We could use .then() and .catch() to build a flatter, more readable async chain. This was much better! But new problems arose. If you forgot to return the next Promise in a .then(), or forgot to re-throw an error in a .catch(), the chain would continue executing in an unexpected way. async/await allows us to write async…  ( 9 min )

Last week, a customer emailed asking if my store was "still in business" because the account dashboard looked "kind of abandoned." That stung. I'd spent $2,000 on a custom theme and countless hours perfecting the product pages, but the moment customers logged into their account, they saw what basically looked like a WordPress admin panel from 2012. The worst part? I knew it was bad. I'd been ignoring it for months. If you're running a WooCommerce store and feeling that same embarrassment every time you think about your account dashboard, this tutorial is for you.

Here's why: Soda is mainly relational data focused; CsvPath Framework is mainly files focused Soda is a data quality tool; whereas, CsvPath Framework is for data preboarding, which includes data quality, but isn't limited to it SodaCL is a domain-specific language built on YAML that uses embedded SQL; CsvPath Validation Language is a first-class stand-alone validation language, more similar in that regard to DDL o…  ( 9 min )

The Journey So Far Python data ecosystem. In previous releases (0.1 through 0.3), I focused heavily on data engineering and machine learning libraries. I had the opportunity to contribute to Dagster, scikit-learn, and NumPy. These experiences were invaluable. I learned how to navigate complex C-extensions in NumPy, understood the orchestration logic in Dagster, and worked through to the strict code standards of scikit-learn. However, I felt this is another time to move out of the box one more time and push me to the new world. Bridging Data and Application Before I jump into anything, I asked myself: Where do I want to be as a developer? I have some background in data processing, but I want to strengthen my skills in building the applications that utilize this data. I want to bridge the ga…  ( 7 min )

Introduction: From Docker Woes to LLM Jailbreaks This case study details the technical journey of setting up a local, self-hosted Large Language Model (LLM)—TinyLlama—on a Raspberry Pi 5 using Ollama and Open WebUI. It culminates in a red team exercise where the model's safety and integrity are tested against common prompt injection and hallucination attacks. The exercise proved that while the model is technically resilient in some areas, it fails catastrophically when subjected to role-play and policy fabrication attacks. The initial goal was simple: get a web UI running for TinyLlama. The primary challenge was wrestling with Docker networking on a Linux host (the Pi). Technical Setup: Hardware: Raspberry Pi 5 (8GB) LLM: TinyLlama (700M parameters) Runtime: Ollama (Docker Container, Por…  ( 8 min )

Most .NET developers first meet ASP.NET Core attribute routing in a happy path like this: [ApiController] [Route("api/[controller]")] public class CategoriesController : ControllerBase { [HttpGet("{id:int}", Name = "GetCategory")] public IActionResult GetCategory(int id) { ... } } Hit F5, the app runs, CreatedAtRoute("GetCategory", ...) works, and everything feels good. Then one day you add API versioning and suddenly your app dies on startup with something like: Attribute routes with the same name 'GetCategory' must have the same template This post will walk you through: What this error really means. Why it appears as soon as you start versioning controllers. Three clean ways to fix it (including when each one makes sense architecturally). How to design versioned routes and route…  ( 12 min )

Everything Wrong With The Fantastic Four: First Steps In 20 Minutes Or Less is a Cinema Sins video that gleefully points out every nitpick and “sin” in the new Fantastic Four movie—drops a few jokes, spoils some moments, and ultimately declares it “sintastic” rather than outright terrible. It kicks off with a shout-out to sponsor BetterHelp (discount link included), because even sin-counting can be stressful. On top of the main feature, Cinema Sins plugs their website, Linktree for all the latest updates, YouTube channels (@TVSins, @commercialsins, @cinemasinspodcastnetwork), a sinful viewer poll, Patreon support, and social hangouts (Discord, Reddit, Instagram, TikTok).

The idea of creating my own personal website—a place where I could share projects I'm working on and document my technical journey—has been on my mind for a long time. But as with many personal projects, it kept getting pushed aside. Finally, I found the time, and here it is: mikula.dev. In this post, I want to share how I built it, what tools I chose, and why. When looking for a site generator, I had a few requirements in mind: it needed to be simple yet flexible, fast, and shouldn't require hours of configuration just to get started. After evaluating several options, I settled on Hugo. Hugo is one of the fastest static site generators out there. Written in Go, it can build thousands of pages in seconds. But speed isn't the only advantage—it generates pure static HTML files, which makes h…  ( 9 min )

Chapter 4: Collections and the Art of Growing Lists Thursday morning brought rain. Ethan arrived at the archive shaking water from his jacket, balancing a coffee tray and a small pastry box. Eleanor glanced up from her laptop. "Wet out there?" "November in New York." He set down the coffees and opened the box. "Rugelach today. Chocolate and cinnamon." "You're learning the neighborhood." She took one and bit into it. "What made you choose rugelach?" "The baker said they're good for thinking. Something about the layers." Eleanor smiled. "Layers. Perfect.

Subscriptions power modern SaaS apps, but integrating payment providers like Stripe requires handling webhooks reliably. In a recent commit to the CommitLore backend, I implemented a full subscription system using Stripe. The standout technical choice was ensuring idempotent webhook processing to avoid duplicate updates during retries or failures. This approach uses a dedicated webhook_events table to track Stripe events and optimistic locking on the subscriptions table to prevent race conditions. It's a practical pattern for any NestJS app dealing with external async events. Let's break it down. Stripe webhooks notify your server of events like subscription upgrades, cancellations, or payment failures. But networks are unreliable—events can arrive multiple times, out of order, or during d…  ( 8 min )

Development environment, staging environment, production environment—it's common to switch between multiple environments. The most critical mistake to avoid is performing actions intended for the development environment in the production environment. As humans, we make mistakes. However, tightening checks excessively can make daily operations cumbersome. AI is still not entirely reliable. So, what should we do? Let's rely on human intuition: color. I refer to this as the Production Color. You should apply a color that clearly indicates it's the production environment. Red is often a good choice. The color change uses client-side features (browser-side). You can use a script engine like Tampermonkey or develop a custom extension. Which part of the screen to change depends on the environment, but you could either fill the entire background or just the header. Of course, you can create this with AI. It may be tedious to customize for each environment, but compared to the effort of fixing mistakes in the production environment and the stress of straining yourself to avoid such mistakes, it's worth it. No more excuses—let's get this done quickly.  ( 6 min )

While working on an Android app, persisting data is a common use case. Take a simple example: an app that supports light and dark themes. If a user toggles between both, we need to remember this preference across lifecycle changes, like when the app is closed and reopened. This theme-setting example highlights a common challenge: choosing the right storage mechanism. Which storage mechanism fits our specific needs while balancing performance, persistence, and security? In this article, we will introduce the two storage areas available to us in Android: internal and external storage. Android separates storage into app-specific (private to the app) and shared storage (visible to other apps). The terms private and shared are not only about encapsulation; they also relate to where files live i…  ( 8 min )

Introduction When you work on a long-term project, you may have experienced situations like: Something unexpected happens and the project drifts far away from the original plan You start a task and suddenly encounter unforeseen issues, which create even more tasks These are what we call “Unknown Unknowns.” The term dates back to a 2002 press briefing by U.S. Secretary of Defense Donald Rumsfeld. In response to questions about whether Iraq possessed weapons of mass destruction, he explained that information falls into three categories: Known Knowns: things we know Known Unknowns: things we know we don’t know Unknown Unknowns: things we don't even realize we don't know He emphasized that the last category is the most troublesome—risks that come from outside our predictions can easily …  ( 7 min )

For years, frontend development has been dominated by the build step. Webpack, Rollup, Vite, PostCSS... the list goes on. While tools like Tailwind CSS revolutionized how we style apps, they introduced a heavy dependency on Node.js environments. If you are a backend developer (PHP, Python, Go) or just want to prototype a quick idea, setting up a full frontend toolchain feels like overkill. I asked myself: What if you could just write HTML? So I built AtomAttr. AtomAttr is a runtime CSS engine. Instead of compiling your CSS at build time, it compiles it in the browser, instantly. It uses a MutationObserver to watch your DOM and injects atomic CSS rules only for the attributes you actually use. It weighs less than 10kb, has zero dependencies, and requires no config.

big awesome problem.... We’ll try to create a compact, practical Kubernetes architecture for a video streaming app at 1 million users, plus clear design choices, components, scaling patterns, and rough capacity guidelines. We’ll also call out assumptions up front to pick the path that matches the traffic pattern. Assumptions (pick the one that matches you) I must assume something because “1 million users” could mean many things: Option A - 1M total registered users, low concurrency: ~10k concurrent peak. Option B - 1M active users, moderate concurrency: ~100k concurrent peak. Option C - 1M concurrent users (extreme): design is close to CDN-first, multiple large clusters, heavy multi-region infra. So lets focus on Option B (100k concurrent) as a realistic high-scale target (and als…  ( 9 min )

I’ve been putting OpenAI’s Codex coding assistant to task. Literally. Codex and I put together a task management system for the open source application DepanFx. The launch customer for these features was asynchronous file loading, a point of notable lag. The new capabilities avoid locking the UX loop, and provide an acceptable UX for notification and tracking of task execution. Before we were done, asynchronous file loading was also added to the session startup execution path. With Codex’s help, I was able to add asynchronous file loading, with robust task management support, in roughly 4 days. All in, including a few more days of expanded functionality and other cleanup, Codex and I were able to bring up almost four thousand lines of new task management software.

Hello fellow front-end engineers! These overly complex components—the "God Components"—violate the fundamental principle of Single Responsibility. They handle too much state, too much logic, and too many concerns. This leads to codebases that are frustrating to work with, slow to test, and expensive to maintain. The Component Responsibility Score (CRS) is a custom, data-driven metric used to quantify how complex and overly scoped a front-end component is. It acts as a health check for component architecture, providing an objective number that signals when a component must be broken down. The goal is simple: The beauty of the CRS is that it focuses on structural and logical properties, not specific API calls (like useState vs. data()). This makes it universally applicable.

Liquid syntax error: Variable '{{% raw %}' was not properly terminated with regexp: /\}\}/  ( 6 min )

Regex (REGular EXpressions) is commonly used in command-line tools, such as grep or sed, in order to search for a pattern or to search and replace a pattern. Regular expressions are a powerful tool whenever there's a "free form" string that needs to be analyzed, or an input from a source that may or may not provide exactly formatted input. Regex is perfect to extract useful bits and pieces from it. In RimStone, Regex is a built-in feature via match-regex statement. Here's an example of using it in a server application: // Use backreferences to swap two words, // with "Reverse order word" as a result match-regex "(word)\\s+(order)" \ in "Reverse word order" \ replace-with "\\2 \\1" \ result res print-out res new-line RimStone regex has a powerful "cache" clause which allows for regex pattern to be parsed once into a binary representation and used over and over without parsing again. In our tests, this often results in five times (5x) or more speed up! This makes it perfect for server applications where performance is paramount. RimStone is overall built for performance, with LTO (Link Time Optimization) built-in across the board, and with generated C code used to create high-performance native applications. No Virtual Machines, no p-code, just native executables. On top of that, RimStone is a memory-safe language. The full regex example, with detailed instructions, can be found here.  ( 6 min )

Walk through your house on a sunny afternoon and you’ll see it: thin beams of light catching thousands of floating specks that weren’t visible a second earlier. That’s not “dirty air.” It’s physics in motion. Every home operates like a small particle system where air moves, slows, collides, rises, sinks, and drops microscopic matter into the places you later have to clean. Dust doesn’t settle randomly. It follows the rules of airflow, temperature differences, pressure zones, humidity, and friction. When you understand those rules, dust becomes predictable, not mysterious. If you live in a dry, dusty region, the effects are even stronger. The principles below apply in every climate, but they show up faster where heat, HVAC usage, and outdoor particulate levels are high. For a deeper look at…  ( 9 min )

The Problem: "I just need a simple database..." We've all been there. You are building a side project, a prototype, or a simple CMS for a client. You need a database, but: Postgres/MySQL feels like overkill (and costs money/effort to host). SQLite is great but hard to share with non-tech clients. Google Sheets is perfect for clients, but the API... well, the API returns untyped arrays (row[0], row[1]), which is a nightmare to maintain.

What is Elixir Script Mode? Elixir Script Mode refers to an early and lesser-used execution style of Elixir where the language could be written and executed like a scripting language rather than as part of a compiled OTP project structure. Instead of working inside Mix projects or OTP application design, Script Mode allowed direct execution of .exs files, similar to how Python or Ruby scripts run. This mode existed mainly for experimentation, rapid prototyping, tooling demos, and small automation tasks. While still supported, it never became the primary style of using Elixir, especially once the language standardised around Mix, Phoenix, and OTP-minded architecture.

What is Glypho? Glypho is an esoteric programming language where programs are written entirely using abstract shapes, glyphs, and symbols rather than alphanumeric characters. Instead of words, numbers, or punctuation, the language uses geometric marks such as circles, arrows, strokes, spirals, and shorthand ideograms to represent instructions. The aesthetic resembles ancient writing systems or UI iconography more than traditional programming syntax. Glypho explores what programming looks like when everything meaningful must be communicated visually rather than linguistically. Language Type: Symbol-based esolang Era: Approx. 2016–2020 experimental period Execution Model: Interpreter reads symbols sequentially or spatially depending on variant Paradigm: Stack-based, rule-based, or direc…  ( 7 min )

What is MicroTape? MicroTape is an ultra-minimal esoteric language inspired by the original concept of Turing tape computation. It strips programming down to only a few operations: moving left or right along a tape, modifying a single cell, and optionally printing or halting. The language exists to demonstrate how little machinery is required to achieve full computational behavior, making it a study tool for Turing completeness and extreme language minimalism. To a human reader, programs appear as short symbol sequences rather than structured code. Language Type: Minimalist tape-based esolang Era: Part of the 2010s minimal language movement Execution Model: Single tape, single pointer Memory Model: Single infinite tape of integers or bytes (variant-dependent) Typing: None — values ar…  ( 7 min )

What is StackCats? StackCats is an esoteric programming language where all operations are represented as cat-themed commands. Instead of symbols or keywords, instructions mimic cat actions such as pawing, sitting, napping, jumping, or meowing — each corresponding to a stack operation. The language combines the structure of a traditional stack machine like Forth or False with a playful lexical theme centered around feline behavior. Programs often look like a series of cat instructions rather than recognizable code, and part of the appeal comes from the absurdity of reading what appears to be a cute pet diary while actually performing computation. Language Type: Esoteric / stack-based command set Era: Mid-2010s community creation wave Execution Model: Single global stack manipulated by c…  ( 7 min )

What is StackCells? StackCells is an esoteric language where memory is represented as a grid of individual stacks rather than a single linear memory tape or one global stack. Each cell contains its own independent stack of values, and execution moves between cells while manipulating the local stack contents. The model is inspired by grid-based execution languages like Befunge but combined with stack-based semantics similar to Forth or False. Instead of thinking in lines of code, the programmer must think spatially about how data flows between stacked memory regions. Language Type: Esoteric / grid + stack machine Era: Experimental language wave (approx. 2016–2020) Execution Model: Cursor moves through grid, operating on cell-local stacks Paradigm: Stack-based, spatial execution, proced…  ( 7 min )

What is TuringTiles? TuringTiles is an esoteric programming language inspired by Turing machine theory, but instead of a single tape and head, programs are represented as grids of tiles. Each tile encodes a rule: when the execution cursor enters from one side, it performs an operation and exits through another side. The program's logic emerges from how these tiles connect, creating a visual, modular, and puzzle-like execution pattern. It behaves somewhere between a cellular automaton, a flow puzzle, and a visual Turing machine. Language Type: Esoteric / visual rule-based language Era: 2014–2019 indie experimentation period Execution Model: Cursor-driven tile map traversal Paradigm: State transition + spatial programming Typing: None — tile symbols control execution A simplified tex…  ( 7 min )

If you’re active in the developer community, you’ve probably noticed one thing over the last week — Gemini 3 is literally everywhere. X (Twitter), Reddit, Discord, YouTube… the hype has been insane. Everyone keeps saying “Google finally did it… this model is massive.” As a developer, I’m always curious when a new AI model gets this kind of attention. So of course, I had to test it myself. Not by asking philosophical questions or doing poetry — but by using it for something real, something practical: 👉 Can Gemini 3 build a usable developer-friendly website from a single prompt? So I opened Google AI Studio, typed a simple request, and the results honestly shocked me. My first test prompt was extremely basic: “Make a doctor appointment landing page website.” Just one line.

Async calls (e.g., fetch()) return Promises, not immediate values. Direct return yields undefined. Focus: JavaScript (adapt for other langs). function fetchData() { let result; fetch('https://api.example.com/data') .then(data => { result = data; }); return result; // undefined } function fetchData() { return fetch('https://api.example.com/data') .then(response => response.json()) .catch(error => { throw error; }); } // Usage fetchData().then(data => console.log(data)); Pros: Non-blocking. Cons: Nesting issues. async function fetchData() { const response = await fetch('https://api.example.com/data'); return await response.json(); } // Usage const data = await fetchData(); console.log(data); Pros: Readable, try/catch errors. Cons: Requires async callers. function fetchData(callback) { fetch('https://api.example.com/data') .then(data => callback(null, data)) .catch(err => callback(err, null)); } // Usage fetchData((err, data) => { if (!err) console.log(data); }); Pros: Simple. Cons: Control inversion. Errors: Always .catch() or try/catch. Parallel: Promise.all([async1(), async2()]). Timeouts: Use AbortController. Testing: Mock fetch in Jest. Node: node-fetch for < v18. const fetch = require('node-fetch'); async function getPosts(userId) { const res = await fetch(`https://jsonplaceholder.typicode.com/posts?userId=${userId}`); return await res.json(); } const posts = await getPosts(1); // Returns array Use async/await for clean returns.

GitHub Home A hacker exploited this vulnerability, bypassed authentication, and stole the entire user table data. By the time we discovered it, it was too late. For the next few months, our entire team lived in nightmares: cooperating with investigations, appeasing clients, fixing vulnerabilities, checking all company projects for similar risks... The company's reputation and business suffered heavy damage. That incident taught me the most profound lesson: in the world of web development, security always comes first. Many developers, especially when project deadlines are tight, view "security" as a "feature module." They say: "Let's implement the main functionality first, and we'll 'add' security features in the next iteration." This is a fatal misunderstanding. Security is not a coat of p…  ( 9 min )

NullPointerException (NPE) is a Java runtime exception thrown when code accesses a null reference (e.g., calling a method on null). Trigger: Attempting to use a null object reference (e.g., null.length()). Type: Unchecked exception; occurs at runtime, not compile time. Example: String name = null; System.out.println(name.length()); // Throws NPE Stack Trace: Points to the line; trace upward for root cause. Uninitialized References: Variables default to null if not set. User user = getUser(id); // Returns null if not found user.getName(); // NPE Null Parameters: Methods receive unexpected null inputs. Collection Access: Null lists/maps or missing keys. Map map = new HashMap(); map.get("key").toString(); // NPE if key absent Method Chains: On…  ( 7 min )

3 simple tricks for managing git histories It took me a while to learn these simple tricks for effectively managing Git histories with just a few commands. In the first article, I explained why clear, structured Git commit messages and cohesiv commits are important or why temporary commits make the history more difficult to read. This time, I will show you how to organise your commits before merging them. This will give you a clean, easy-to-understand commit history. Changes should be reviewed and consolidated into a clear commit history. The aim is to include only changes that are relevant, just like book authors revise drafts before publishing. Consider cleaning up commit history for clarity and maintainability: Add changes directly to the previous commit git commit --amend Consolidate…  ( 9 min )

I'm a Python developer who takes pride in writing code that's more readable and less ambiguous or failure prone. Therefore, it was a never-before seen adventure for me, a journey of treading unknown terrains of JavaScript to get this extension working. Now, as for the motive that lead to this moment, I was downloading some large files from sites online as a part of my research, and I was disappointed to see that the native download manager wouldn't handle downloads for my use case right. I mean, due to server download speeds, my network's speeds, or whatever else, some of my downloads would stall, and I'd have to manually be there to resume them so they wouldn't give up on me. So, my eyes on the screen most of the time, or they would just fail, and some that wouldn't resume due to the link…  ( 10 min )

SECTION 1 — The Past: The Origin Story of SQL Before we talk about a new query language for networks, we have to pay respect to the old one — the one that defined how the entire digital world thinks about data. Because SQL wasn’t just a technology. And to understand why N-SQL exists, we have to rewind to the beginning. 1.1 — Why SQL Was Born The early 1970s were chaos in data land. Every company wrote its own custom data access systems: hierarchical stores pointer-based network models vendor-specific query languages bespoke storage formats This meant: no uniform way to access data no shared mental model no predictable structure and every enterprise was basically reinventing the wheel Then Edgar F. Codd walked in with a banger of a paper: Codd’s idea was wild for the time: treat data as uno…  ( 28 min )

Writing good code is hard. The industry's response has been to create an ever-growing catalog of design patterns, principles, and architectural guidelines. While these have their place, there's a simpler practice that yields better results: writing tests. Let's start with something simple. You need to build a function that calculates the total price of items in a shopping cart, including tax. That's it. A straightforward requirement. Let's see how this can go wrong when we think in patterns first, and how tests lead us to better design. The first instinct is often to create a class. class ShoppingCart { private items: CartItem[] = []; addItem(item: CartItem): void { this.items.push(item); } getItems(): CartItem[] { return this.items; } } The thought process: "A cart ha…  ( 13 min )

In the last few months, I have been very interested in large language models. At the same time, the GPU world is also changing. Nvidia is still the market leader, but AMD, Intel, and even Chinese companies are making cheaper GPUs. The main challenge is that CUDA is still the dominant software stack, and Nvidia drivers are not open source. Because of this, using non‑Nvidia GPUs is still not smooth. As someone who runs a homelab, I wanted a setup where I can use different GPUs together. But even mixing two Nvidia GPUs of different generations is hard. If you upgrade from RTX 3090 to RTX 5090, you may need a different CUDA version, a different Python version, and a different PyTorch version. New architectures like Blackwell also take time to enter mainstream frameworks. So many people end up …  ( 16 min )

Cloud data warehouses are amazing for production. They are terrible for development. If you’re a Data Engineer, you know the pain of the “cloud feedback loop”: You write a complex SQL query. You hit “Run” in your orchestrator. You wait 45 seconds for the warehouse to spin up or queue your job. It fails because of a syntax error. You fix it. You pay for the query slot. You wait again. This latency kills flow. In software engineering, we run code locally on our laptops before shipping to production. Why can’t we do the same for data pipelines? I built FastFlowTransform (FFT) to solve this. It’s a framework that lets you build and test your pipeline locally using DuckDB (for speed and free compute), and then deploy the same project to Snowflake, BigQuery, or Databricks for production.

From Single Files to Complete Directory Trees—A Fundamental Evolution Posted by Muhammed Shafin P (HejHdiss) | Qeltrix Project Lead I'm thrilled to announce Qeltrix V5, the most significant architectural evolution in the Qeltrix ecosystem.

What is deboa-macros? deboa-macros is a procedural-macro crate for Rust that builds on top of the core HTTP client deboa. Its goal is to simplify common HTTP request patterns using expressive macros---turning verbose boilerplate into concise, type-safe code. Where deboa provides low-level HTTP capabilities (HTTP/1 + HTTP/2, async runtimes like Tokio or Smol, etc.), deboa-macros layers ergonomic syntax on top so you can focus on logic instead of deboa-macros Rust's procedural macros allow developers to run code at compile time to generate boilerplate, enforce patterns, and create domain-specific syntax. For HTTP requests, much of the code is repetitive: building the request serializing bodies deserializing responses handling errors deboa-macros addresses these pain points with: …  ( 7 min )

I recently built a prospecting agent with Python to find local businesses on Google’s lower-ranked pages and pitch them SEO services. The initial version was... promising but flawed. It tried to pitch Indeed.com because they didn't have a local phone number. It told Ford Dealerships their site was "down" because their firewall blocked my bot. It sent robotic emails starting with "Fail: H1 Missing" ... not exactly a charming opener. I realized that to make this tool useful, I needed to move from a simple scraper to a true agent.

OK, so... For those using the Perl Catalyst web framework in ways involving structured request bodies (e.g. API POSTs)... $c->req->body is a string, unless Content-Type is application/x-www-form-urlencoded, text/xml, or multipart/form-data (or in fact application/json, which isn't in the docs), in which case it's a File::Temp (an overloaded file handle), and $c->req->body_data gets you the deserialised body. For various reasons, largely to do with the idiosyncrasies of one particular module, I need to read the raw body data from the $c->req->body file handle to process a Stripe webhook payload. For various other reasons, as part of the API call logging, I need to call $c->req->body_data to get at the deserialised body in another module. You may imagine my delight when adding the latter caused the former to fail. An afternoon of bad language and extra debug eventually revealed that $c->req->body_data doesn't clean up after itself, and I have to seek( $c->req->body, 0, 0) before I can read any data from the body file handle. If this is useful to anyone else, you have my sympathies.  ( 6 min )

What is CutMix? CutMix, introduced in 2019, takes Cutout’s idea and dials it up: Instead of dropping pixels, it replaces them with content from a different image and mixes the labels accordingly. You cut a patch from image A, paste it onto image B, and assign the new image a label proportional to the visible region. Cutout removes. CutMix sits in the middle of that spectrum. Why does replacing a patch help? Because it attacks two problems at once: Localization bias Data inefficiency And unlike Mixup (which we'll get to), CutMix preserves crisp local structure, the pasted region is still an actual object patch, not an interpolation. Why isn’t this harmful? CutMix works because: The model learns that objects may appear in strange positions It reduces overfitting to backgrounds or canonical object placements It provides a natural form of regularization via mixed-label supervision It improves both robustness and calibration CutMix is also surprisingly stable, its patch operation doesn’t degrade image quality as much as one might expect. When does CutMix falter? CutMix can struggle when: Training data is already extremely diverse Spatial coherence is critical (e.g., segmentation tasks) Pasted regions occlude too much semantic content The patch sampling is too aggressive Still, for classification pipelines, CutMix is often a plug-and-play upgrade. CutMix is Cutout with context: Next: Mixup, the method that abandons spatial structure entirely and asks the model to learn through interpolation.  ( 7 min )

As a frontend developer, much of my job is converting Figma designs into React code—a process that’s both meticulous and repetitive. Every pixel, color, font weight, spacing, and padding has to match the designer’s intent exactly. It can be satisfying when it comes together, but it’s also a huge time sink. Naturally, to save time and speed up my workflow, I’ve tried out various tools that promise to automate the conversion from Figma to React. But most of them ended up creating more cleanup work than they saved. Then I tried Kombai — and the difference was immediately clear. Unlike most generic code generators I’ve tried, Kombai is the only frontend-specific AI agent I can genuinely vouch for that actually understands frontend development and produces code I’d write myself, not code I need…  ( 20 min )

How we're adding hardware security to a formally verified 2 of 3 consensus system across Arbitrum, Solana, and TON. 78 Lean proofs. Zero external dependencies. I've spent 3 years building Trinity Protocol a 2 of 3 multi-chain consensus system that distributes trust across Arbitrum, Solana, and TON. When a community member suggested adding Trusted Execution Environments (TEE), I researched the options: Oasis ROFL: $100-150/month, vendor lock-in Cloud TEE (Azure, GCP): $200-300/month, external dependency Phala Network: Third-party infrastructure None of these fit our philosophy.

I had to redo the entire SCIM validator journey after we've migrated to a new company. This article shares the practical lessons from that rework: tightening concurrency, adding hybrid caching, clarifying when /Schemas actually matters and structuring validation runs so progress is repeatable instead of guesswork. SCIM still promises automated provisioning from an IdP, but the path to a production-grade, Entra-compatible implementation is about disciplined iteration, not just “passing the tests.” Once integrated, lifecycle events (create, update, deactivate) flow from your IdP without manual admin work, improving security posture and reducing bespoke connector logic. Interoperability hinges on spec fidelity: consistent status codes, predictable resource representation, correct filtering, a…  ( 9 min )

Self-corrective Code Generation is an advanced AI approach where code is not only generated but also continuously refined based on feedback and predefined rules. Unlike traditional methods, this process ensures that code meets essential standards for readability, efficiency, maintainability, and compliance with coding guidelines. This article will explore how AI-generated code can be incomplete without proper validation, the consequences of using untested code, and how self-corrective code generation solves these challenges. We will also discuss advanced techniques, like multi-step agents, to further enhance code quality, followed by practical examples of how this process works. 1. Sources of Incomplete Code There are two main sources of incomplete code originating from AI’s output.  Limit…  ( 12 min )

Introdução O escalonamento tradicional baseado em CPU ou memória atende bem a diversos cenários, mas pode apresentar limitações em aplicações que sofrem bursts de requisições ou que exibem padrões de tráfego irregulares. Nesses casos, é comum que a aplicação mantenha níveis estáveis de CPU e memória ao mesmo tempo que enfrenta pressão direta no atendimento HTTP, gerando aumento de latência, formação de filas e redução de throughput antes que o autoscaler identifique a necessidade de ajuste. O KEDA HTTP Add-on foi desenvolvido para lidar com essas situações ao permitir que o escalonamento considere o volume de requisições como métrica primária. Essa abordagem oferece uma resposta mais alinhada ao comportamento real da carga, especialmente em serviços sensíveis a variações rápidas de deman…  ( 10 min )

A practical, human-first guide to getting better results from AI tools If you’ve experimented with AI while planning a new software project, you’ve probably noticed a pattern: sometimes the output is sharp, actionable, and genuinely helpful—and other times it feels vague or generic. The difference usually comes down to one thing: the quality and structure of your prompt. The good news is that writing a great prompt is not about being poetic or overly verbose. It is about giving the AI the same level of clarity you'd expect from a teammate. In this post, I’ll share a practical approach you can use to consistently get detailed, high-value results. Building software is messy in the best kind of way. There are tradeoffs, constraints, unknowns, and assumptions scattered everywhere. When your pr…  ( 8 min )

That's wild confidence. That's believing you're worth that kind of commitment from another human. I don't have that. The arrogance to think I deserve that or that it's even possible.

Most AI tools wait for a prompt. Agentic AI works differently — it takes a goal, plans the steps, and executes tasks on its own. That small change is starting to reshape developer workflows. What developers are already using agents for: Parsing docs and explaining APIs Running data analysis without manual queries Automating reporting and monitoring Debugging suggestions from logs and errors Repetitive tasks like test generation or KPI checks It’s not about replacing developers. As models get better at reasoning and tool-use (Python, SQL, APIs), agentic workflows will quietly become part of everyday engineering work.

If a variable has more than 30% missing values, I treat it carefully because that much missing information can weaken the model. First, I try to understand the cause: is it random, system-driven, or does it follow some pattern? Knowing this helps me decide if the feature is still useful. If the column doesn’t provide strong value, the safest choice is to drop it. For important variables, I look at different imputation methods. Numeric fields might use median or interpolation, while categorical fields can use mode. If the feature is valuable but tricky, I may use advanced methods like KNN imputation or model-based imputation to estimate missing values. Sometimes missing values are meaningful on their own, for example, “not filled because user didn’t use the feature.” In those cases, I keep the column and also create a separate flag like “is_missing” to capture that information. The goal is to keep the dataset balanced, clean, and meaningful without forcing incomplete or low-quality data into the modeling process.  ( 6 min )

Imbalanced data means the classes in your dataset are not represented equally. One category has a lot of samples, while the other has very few. For example, imagine a medical dataset where 95% of patients are healthy and only 5% have a rare disease, that’s clearly imbalanced. The issue is that models trained on such data tend to learn the “easy pattern,” which is predicting the majority class every time. This makes the accuracy look high, but the model is actually useless for detecting the minority class, which is often the most important one. To handle this, I use techniques like oversampling the minority class (SMOTE), undersampling the majority class, using class-weighted algorithms, or choosing models that naturally handle imbalance better. I also focus more on metrics like F1-score, recall, and precision rather than plain accuracy. In my experience, dealing with imbalance is less about forcing the data to look “perfect” and more about making sure the model pays attention to what truly matters. A little extra care here can dramatically improve real-world predictions, especially when the minority class carries the real risk or value.  ( 6 min )

GitHub Home A recent enterprise-level system project made me deeply realize that a truly production-ready framework should provide complete solutions for the entire application lifecycle. My recent experience with hyperlane framework showed me the concrete embodiment of ideal production-ready features.

Your payment integration just went live. Everything worked perfectly in staging. Then, when real users started transacting, they were unsuccessful. Customers can't complete purchases, support tickets flood in, and your business starts losing revenue. This is a situation you don’t want to find yourself in, and you won’t if you test your payment gateway properly. Failed payments cost businesses $118.5 billion annually, according to this 2020 report, and most failures could have been caught with proper testing of your payment processor integration. Unlike bugs that frustrate users, payment failures directly cost you money and trust. This guide shows you how to test payment integrations properly.

A quick maintenance release for the GitHub Action for Checking Spelling was made yesterday. The other day the repository got a new issue which requested enabling of use of large Aspell dictionaries. The GitHub action however is just a wrapper for PySpelling so I sent the user in that direction, also because this was something I believe was more in the realm of PySpelling than the GitHub Action. Not long after a new release of PySpelling (2.12.1) was made, so I reopened the issue, since I needed to update the action with the new release to meet the need of the user and the original request and it was easier to keep track of the request this way. Later the user wrote to me: Thanks! I’m amazed at how quickly the guy over at PySpelling made the change and release. Hmmmmm... I decided to step my game up and luckily I had an window of opportunity, so I made the release numbered 0.55.0 which contains an update of the core component PySpelling from version 2.12.1. At this time I am not sure how the Aspell setting for large dictionaries is enabled/configured, I have not been able to find any documentation on this, but at least the action is aligned with the core component - I hope this works out for the user.

Java copySign() Method: Finally, Take Control of Your Number's Sign Alright, let's talk about one of those "hidden gem" methods in Java that doesn't get the spotlight it deserves. We're diving deep into Math.copySign(). Ever been in a situation where you have a number, and you need its magnitude (the value without the sign) but with the sign of another number? If you've ever tried to do this manually with if conditions and multiplication, you know it's clunky. It's one of those things that makes your code look... well, a bit amateurish. That's where Java's copySign() method swoops in to save the day. It’s a simple, elegant, and powerful tool for manipulating the signs of floating-point numbers.

My Journey From No-Code to Real Product Design When I first started building things, I wasn’t writing code. I began with no-code tools — simple drag-and-drop platforms that helped me bring ideas to life without touching a text editor. And looking back, that phase was more important than I realized. This is the story of how no-code gave me the confidence to create, and how that journey slowly pushed me toward UI design, and eventually into real development. The No-Code Curiosity At the beginning, all I wanted was to build something that worked. Webflow, Bubble, Glide, Notion databases — these tools felt magical. I could build: Landing pages Simple dashboards Forms Mini web apps Automations …all without typing a single line of code. And here’s the truth: no-code didn’t limit me — it unlocked me. How pages connect How components repeat How data flows What makes a UI feel “clean” vs “cluttered” How users navigate Before writing code, I learned how to design with intention. Here are the biggest takeaways: 1️⃣ No-code is not “lesser” — it’s training wheels for product thinking 2️⃣ Design becomes easier when you’ve built things yourself 3️⃣ Moving to code becomes natural once you know why you’re building 4️⃣ Your first goal shouldn’t be to become a “developer” It should be: solve a problem beautifully.  ( 7 min )

Mastering layouts in Vue.js is a milestone that separates beginners from intermediate developers. When you first start, you likely wrap every page in a and component. It works, but it’s repetitive and destroys component state every time you navigate. This guide explores "Smart Layouts", a set of patterns that make your Vue application more maintainable, performant, and capable of advanced behaviors like persistent state (think Spotify’s audio player that doesn't stop when you change pages). Most developers start here. As expert Vue.js developers know, you create a DefaultLayout.vue and manually wrap every single page content with it Home Page The Problem: Home to About, t…  ( 8 min )

updating the screen: import { useState } from 'react'; your component to “remember” some information and display it. function MyButton() { const [count, setCount] = useState(0); initial state of count is 0 if you change the state use setCount function MyButton() { const [count, setCount] = useState(0); function handleClick() { setCount(count + 1); } return ( Clicked {count} times ); } when you click the button the current state is updated using the setCount is increased. Hook: export default function MyApp() { const [count, setCount] = useState(0); function handleClick() { setCount(count + 1); } return ( Counters that update together ); } the button is clicked upadted the state count together.use the information pass down this is called props. function MyButton({ count, onClick }) { return ( Clicked {count} times ); } count and onclick is a props of parents component it is pass the button. The new count value is passed as a prop to each button, so they all show the new value. This is called “lifting state up”  ( 6 min )
